The ounce (symbol: oz, from Italian onza) is a unit of mass equal to exactly 1/16 of an avoirdupois pound, which is 28.349523125 grams in the metric system.
Avoirdupois Ounce vs. Troy Ounce
When Americans say "ounce" in everyday life, they almost always mean the avoirdupois ounce (28.35 g). However, there's a second type of ounce:
Avoirdupois Ounce (Standard Ounce):
- 28.35 grams
- Used for: food, cooking, postal weight, groceries, body weight, general commerce
- 16 ounces = 1 avoirdupois pound
Troy Ounce:
- 31.10 grams (about 10% heavier)
- Used exclusively for: precious metals (gold, silver, platinum), gemstones, gunpowder
- 12 troy ounces = 1 troy pound
- Abbreviated: "oz t" or "ozt"
Critical distinction: When buying gold or silver, prices are quoted per troy ounce (31.1 g), not avoirdupois ounce (28.35 g). A troy ounce is about 2.75 grams heavier than a standard ounce.
Ounce vs. Fluid Ounce
This is one of the most common sources of confusion in American cooking:
Ounce (oz): Measures weight/mass
- Used for solid or bulk ingredients: flour, sugar, meat, cheese
- 1 oz = 28.35 grams
- Measured with a scale
Fluid Ounce (fl oz): Measures volume/capacity
- Used for liquids: water, milk, juice, oil
- 1 fl oz = 29.57 milliliters (US) or 28.41 mL (UK)
- Measured with measuring cups
When they happen to match: For pure water at room temperature, 1 fluid ounce weighs approximately 1 ounce. This coincidence often misleads people into thinking oz and fl oz are interchangeable—they're not.
Example of the difference:
- 8 fl oz of water weighs about 8 oz
- 8 fl oz of honey weighs about 12 oz (honey is denser)
- 8 fl oz of olive oil weighs about 7.3 oz (oil is less dense)
Mathematical Relationships
1 ounce equals:
- 1/16 of a pound (exactly)
- 28.349523125 grams (exactly)
- 0.028349523125 kilograms
- 437.5 grains (grain is an even smaller unit)
- 28,349.523125 milligrams
Common fractions of a pound:
- 1 oz = 1/16 lb = 0.0625 lb
- 4 oz = 1/4 lb = 0.25 lb (quarter-pound)
- 8 oz = 1/2 lb = 0.5 lb (half-pound)
- 12 oz = 3/4 lb = 0.75 lb
- 16 oz = 1 lb (full pound)
A microgram (symbol: µg or mcg) is a unit of mass in the metric system equal to one millionth (1/1,000,000) of a gram, or one thousandth (1/1,000) of a milligram.
Key relationships:
- 1 microgram = 0.000001 grams (g)
- 1 microgram = 0.001 milligrams (mg)
- 1,000 micrograms = 1 milligram
- 1,000,000 micrograms = 1 gram
- 1 microgram ≈ 0.0000000353 ounces
Symbol variations:
- µg: Standard scientific symbol (µ = Greek letter mu)
- mcg: Common in medicine/pharmacy (avoids confusion if µ looks like m)
- Both mean exactly the same thing
The prefix "micro-":
- From Greek "mikrós" meaning "small"
- SI prefix denoting 10⁻⁶ (one millionth)
- Also used in: micrometer (µm), microsecond (µs), microliter (µL)
In perspective (how small is it?):
- 1 grain of table salt ≈ 1,000 µg (1 mg)
- 1 speck of dust ≈ 1-10 µg
- Human red blood cell ≈ 100 µg
- A typical dose of Vitamin B12 ≈ 2.4 µg
⚠️ CRITICAL SAFETY WARNING: Never confuse µg (microgram) with mg (milligram). Taking 1 mg when prescribed 1 µg = 1,000x overdose! Always double-check labels and prescriptions.
Note: The Ounce is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Microgram belongs to the metric (SI) system.
History of the Ounce and Microgram
Roman Origins: The Uncia
Latin Etymology: The word "ounce" comes from the Latin "uncia," meaning "one-twelfth" (related to "inch," from the same root).
Roman Measurement: In ancient Rome, the uncia was 1/12 of a Roman pound (libra), approximately 27 grams. The Romans used base-12 (duodecimal) systems for many measurements.
Symbol Origin: The abbreviation "oz" comes from the medieval Italian word onza (ounce), not from any English word starting with "o" and "z."
Medieval European Variation
Regional Chaos: Throughout medieval Europe, dozens of different "ounces" existed, varying by region, city, and trade guild. An ounce in Paris differed from an ounce in London, Venice, or Amsterdam.
Two Main English Systems:
Troy System (for precious goods):
- Used for gold, silver, jewels, and later gunpowder
- Troy ounce: 31.1 grams
- 12 troy ounces = 1 troy pound
- Named after Troyes, France, site of important medieval trade fairs
Avoirdupois System (for bulk goods):
- From French avoir de pois ("goods of weight")
- Used for wool, grain, cheese, meat—everyday bulk commodities
- Avoirdupois ounce: 28.35 grams
- 16 avoirdupois ounces = 1 avoirdupois pound
- Developed by medieval merchants for practical trade
English Standardization
1300s-1500s: Gradual Standardization: English monarchs attempted to standardize weights and measures, but variation persisted.
1588: Queen Elizabeth I: Confirmed the avoirdupois system for general trade, establishing 16 ounces per pound for commerce.
Troy System Preserved: The troy ounce remained the standard for precious metals, a tradition maintained to this day.
1959: International Agreement
Modern Definition: The 1959 international yard and pound agreement between the United States, United Kingdom, Canada, Australia, New Zealand, and South Africa defined:
- 1 pound (avoirdupois) = exactly 453.59237 grams
- 1 ounce (avoirdupois) = exactly 1/16 pound = 28.349523125 grams
This eliminated minor variations between US and British measurements and anchored imperial units to the metric system.
-
Metric System Origins: The microgram is derived from the gram, a base unit in the early metric system defined in the late 18th century during the French Revolution (1790s).
-
Prefix Development: The prefix "micro-" (symbol: µ) was formalized in the late 19th century as part of the systematic development of metric prefixes to indicate a factor of 10⁻⁶ (one millionth).
-
Scientific Need: As analytical chemistry and biology advanced in the 19th and early 20th centuries, scientists needed to measure increasingly smaller masses - leading to widespread adoption of the microgram.
-
Pharmaceutical Revolution: The microgram became critically important in the 20th century with:
- Development of potent hormones (thyroid, insulin)
- Discovery of vitamins requiring trace amounts
- Creation of modern pharmaceuticals with precise dosing
- Antibiotics and specialized medications
-
Vitamin Discovery Era (1910s-1940s):
- Scientists discovered vitamins needed in microgram quantities
- Vitamin B12, biotin, folate measured in µg
- Nutrition labels began using micrograms
- Public health campaigns addressed micronutrient deficiencies
-
Symbol Standardization:
- µg adopted as standard scientific notation
- mcg introduced in medical settings to prevent confusion (µ can look like m if handwritten poorly)
- Both symbols officially recognized and equivalent
-
Modern Usage: Today, micrograms are essential in:
- Pharmaceutical dosing (especially endocrinology)
- Nutritional labeling (vitamins, minerals)
- Environmental monitoring (air/water quality)
- Toxicology and forensic science
- Analytical chemistry (trace analysis)
Common Uses and Applications: ounces vs micrograms
Explore the typical applications for both Ounce (imperial/US) and Microgram (metric) to understand their common contexts.
Common Uses for ounces
Cooking and Baking
Recipe Measurements: American recipes commonly specify ingredient weights in ounces:
- Dry ingredients: flour, sugar, chocolate chips, nuts
- Solid fats: butter, shortening, cream cheese
- Proteins: chicken breasts (6 oz), ground beef (12 oz)
Kitchen Scales: Digital kitchen scales display weight in ounces (and grams), allowing precise measurement:
- Toggle between oz and g
- Tare function to zero out container weight
- Precision to 0.1 oz or 1 gram
Baker's Preference: Professional bakers prefer weight (ounces) over volume (cups) because:
- More accurate and consistent
- Eliminates measurement errors
- Works regardless of how ingredients settle or compact
Grocery Shopping and Pricing
Price per Pound, Sold by Ounce: Many items are priced per pound but sold in ounce quantities:
- Deli meat: "$8.99/lb, customer orders 6 oz"
- Cheese: "$10.99/lb, customer gets 4 oz"
- Bulk nuts: "$12.99/lb, customer takes 8 oz"
Nutrition Labels: US food labels show serving size in both household measures and ounces:
- "Serving Size: 3/4 cup (30g, about 1 oz)"
- This allows people to weigh food if they don't have measuring cups
Comparison Shopping: Savvy shoppers compare unit prices (price per ounce) to find better deals:
- Large box cereal: $0.25/oz
- Small box cereal: $0.35/oz
- Buying larger sizes often reduces cost per ounce
Postal Services and Shipping
USPS Pricing Tiers: First-Class Mail costs increase per ounce:
- 0-1 oz: $0.68 (2024 rate)
- 1-2 oz: $0.92
- 2-3 oz: $1.16
- 3-3.5 oz: $1.40
Package Weight Categories:
- Under 1 pound: priced per ounce
- Over 1 pound: typically priced per pound
Shipping Strategy: Sellers carefully package items to stay under weight thresholds, sometimes removing extra packaging to save an ounce.
Precious Metals and Jewelry
Troy Ounce Standard: Gold, silver, platinum, and palladium are traded globally in troy ounces:
- Gold price: "$2,050 per troy ounce" (example)
- Silver price: "$25 per troy ounce" (example)
- Bullion bars marked in troy ounces (1 oz, 10 oz, etc.)
Jewelry Weights: Precious metal jewelry is often described by weight:
- "14K gold chain, 0.5 troy oz"
- "Sterling silver bracelet, 1.2 troy oz"
Investment: Investors buy gold/silver coins and bars measured in troy ounces (1 oz American Gold Eagle, 5 oz silver bar).
Medical and Healthcare
Infant Weight: Hospitals and pediatricians measure newborn weight in pounds and ounces:
- Birth weight: "7 pounds 6 ounces"
- Weight checks: tracking gains of 4-6 oz per week
- Feeding goals: "baby should gain 5-7 oz weekly"
Medication Dosing: Some medications dose by body weight:
- Pediatric doses calculated per pound or per ounce
- Conversion to metric (kg) for precise dosing
Nutrition and Dietetics: Dietitians often recommend portion sizes in ounces:
- "3 oz serving of protein" (deck of cards size)
- "1 oz serving of cheese" (pair of dice size)
Portion Control and Diet
Standard Serving Sizes:
- Meat/fish: 3-4 oz (cooked)
- Cheese: 1-1.5 oz
- Nuts: 1 oz (small handful)
- Pasta: 2 oz dry per serving
- Cereal: 1 oz (varies by type; check label)
Visual Cues for Ounces:
- 3 oz meat = deck of playing cards
- 1 oz cheese = pair of dice
- 1 oz nuts = small handful
- 2 oz pasta = fits in cupped palm
When to Use micrograms
The microgram is essential for measuring extremely small quantities across multiple fields:
Medicine & Pharmaceuticals
Measuring dosages of potent medications and hormones where milligrams would be too large a unit. Critical for endocrinology, psychiatry, and specialized therapeutics.
Why micrograms matter:
- Potent drugs have narrow therapeutic windows
- Prevents overdose from rounding errors
- Allows fine-tuning of hormone replacement
- Essential for pediatric dosing
Common medications in µg:
- Thyroid hormones (25-200 µg)
- Birth control (15-35 µg estrogen)
- Vitamin B12 supplements (100-1,000 µg)
- Folic acid (400-800 µg)
- Digoxin (62.5-250 µg)
⚠️ Safety: Pharmacists use mcg (not µg) on prescriptions to prevent µ being misread as m.
Convert medication doses: µg to mg | mg to µg
Nutrition
Specifying amounts of trace minerals and vitamins in food, especially those needed in very small quantities but essential for health.
Nutrients measured in µg:

Additional Unit Information
About Microgram (µg)
How many micrograms are in a milligram?
There are 1,000 micrograms (µg) in 1 milligram (mg).
Conversion:
- 1 mg = 1,000 µg
- To convert mg to µg: multiply by 1,000
- To convert µg to mg: divide by 1,000
Examples:
- 0.5 mg = 500 µg
- 1.5 mg = 1,500 µg
- 0.025 mg = 25 µg
- 10 mg = 10,000 µg
Memory aid: "Milli" is bigger than "micro" - mg is 1,000 times larger than µg.
Use our mg to µg converter for instant conversions.
How many micrograms are in a gram?
There are 1,000,000 micrograms (µg) in 1 gram (g).
Calculation: 1 g = 1,000 mg, and 1 mg = 1,000 µg, therefore: 1 g = 1,000 × 1,000 µg = 1,000,000 µg
Conversion:
- 1 g = 1,000,000 µg
- To convert g to µg: multiply by 1,000,000
- To convert µg to g: divide by 1,000,000
Examples:
- 0.001 g = 1,000 µg
- 0.01 g = 10,000 µg
- 0.1 g = 100,000 µg
- 1 g = 1,000,000 µg
Perspective: A grain of salt (~1 mg) contains ~1,000 µg.
What is the symbol for microgram?
The standard symbol is µg (using the Greek letter µ, pronounced "mu").
Alternative symbol: mcg (used especially in medical contexts)
Why two symbols?:
- µg: Standard scientific notation, internationally recognized
- mcg: Safer in medical prescriptions - prevents µ being misread as m
- Both mean exactly the same thing: 1 µg = 1 mcg
Safety issue:
- Handwritten µ can look like m
- "µg" misread as "mg" = 1,000x dosing error
- Medical professionals prefer "mcg" to prevent fatal errors
How to type µ:
- Mac: Option + M
- Windows: Alt + 230
- Or just type "mcg" in medical contexts
Is µg the same as mcg?
Yes! µg and mcg mean exactly the same thing.
- µg: Microgram (using Greek letter µ)
- mcg: Microgram (using letters m-c-g)
- Both = 0.001 mg = 0.000001 g
Why both exist?:
- µg: Standard in science, chemistry, environmental science
- mcg: Preferred in medicine/pharmacy for safety
- Prevents µ being misread as m (which would be mg)
Where you'll see each:
- µg: Scientific papers, environmental reports, lab results
- mcg: Prescription bottles, medical records, pharmacy labels
- Both: Nutrition labels (may show either or both)
Important: Always verify which unit - never assume!
How much is 1 microgram visually?
1 microgram is EXTREMELY small - too small to see with the naked eye.
Visual comparisons:
- 1,000 µg = 1 mg = 1 grain of table salt
- 100 µg = Approximate weight of a human red blood cell
- 10 µg = Large grain of pollen
- 1 µg = Small speck of dust
Perspective:
- 1 paperclip ≈ 1,000,000 µg (1 gram)
- 1 grain of salt ≈ 1,000 µg (1 mg)
- 1 eyelash ≈ 10-100 µg
- 1 human hair (1 cm) ≈ 60-90 µg
For medication:
- A typical Vitamin B12 tablet (1,000 µg) looks like any small pill
- The active ingredient weighs 1 mg
- The rest is filler/binder
You cannot "see" individual micrograms - you need a precision scale to measure them accurately.
What medications are dosed in micrograms?
Many potent medications use microgram dosing:
Thyroid Hormones (most common):
- Levothyroxine: 25-200 µg
- Liothyronine: 5-50 µg
Hormonal Medications:
- Birth control pills: 15-35 µg estrogen
- Testosterone: Some formulations
Cardiovascular:
- Digoxin: 62.5-250 µg
- Clonidine: 100-600 µg
Pain Management:
- Fentanyl: Patches deliver µg/hour
- (Fentanyl is EXTREMELY potent - µg doses)
Vitamins (technically supplements):
- Vitamin B12: 100-5,000 µg
- Vitamin D: 10-125 µg (400-5,000 IU)
- Folate: 400-800 µg
- Biotin: 30-10,000 µg
Why micrograms?:
- Very potent drugs need small doses
- Narrow therapeutic window
- Prevents overdose from measurement errors
⚠️ Safety: These medications have microgram-level dosing precisely because they're potent. Never adjust dose without medical supervision.
How do I measure micrograms at home?
Short answer: You generally CAN'T and SHOULDN'T measure micrograms at home.
Why not?:
- Kitchen scales: Accurate to 1 gram (1,000,000 µg) - NOT precise enough
- Jewelry scales: Accurate to 0.01-0.1 g (10,000-100,000 µg) - still not precise
- Milligram scales: Accurate to 1 mg (1,000 µg) - closer but not µg-level
- Microgram precision: Requires laboratory analytical balance ($1,000-$10,000)
For Medications:
- ✅ Use pre-measured tablets/capsules - safest option
- ✅ Follow prescription exactly - don't compound at home
- ✅ Liquid medications: Use provided dropper/syringe
- ❌ Never try to measure powder medications at home
For Supplements:
- Buy pre-dosed pills (e.g., 1,000 µg B12 tablets)
- Use products with certified dosing
- Don't buy raw powder unless you're a lab
If you need microgram precision:
- Laboratory analytical balance required
- Calibrated weights for accuracy
- Controlled environment (no air currents)
- Cost: $1,000+ for quality balance
Safety warning: ⚠️ For medications, NEVER attempt home measurement. Fatal dosing errors possible. Always use professionally prepared medications.
What's the difference between µg/mL and mg/L?
They are exactly the same!
µg/mL = mg/L (both equal parts per million in water)
Why?:
- 1 mL = 0.001 L (or 1 L = 1,000 mL)
- 1 mg = 1,000 µg
- Therefore: 1 mg/L = 1,000 µg/1,000 mL = 1 µg/mL
Examples:
- Lead in water: 15 µg/L = 0.015 mg/L
- Drug concentration: 100 µg/mL = 100 mg/L
- Vitamin solution: 50 µg/mL = 50 mg/L
Common uses:
- µg/mL: Laboratory concentrations, drug solutions
- mg/L: Environmental standards, water quality
- Both: Used interchangeably depending on field
Parts per million (ppm):
- In water: 1 ppm = 1 mg/L = 1 µg/mL
- In air: 1 ppm is different (depends on molecular weight)
How many IU is a microgram?
It depends on which vitamin! IU (International Units) convert differently for each substance.
Vitamin D (most common):
- 1 µg = 40 IU
- 1 IU = 0.025 µg
Common Vitamin D conversions:
- 400 IU = 10 µg
- 800 IU = 20 µg
- 1,000 IU = 25 µg
- 2,000 IU = 50 µg
- 5,000 IU = 125 µg
Vitamin A (retinol):
- 1 IU ≈ 0.3 µg retinol
- 1 µg retinol ≈ 3.33 IU
Vitamin E (α-tocopherol):
- 1 IU ≈ 0.67 mg α-tocopherol
- (Note: mg not µg for Vitamin E!)
Why different?:
- IU measures biological activity, not mass
- Each vitamin has different potency
- Historical measurement system
- Modern labels often show both µg and IU
Tip: Check supplement labels - most show both µg and IU for clarity.
What is µg/dL in blood tests?
µg/dL = micrograms per deciliter - commonly used in blood test results.
What it means:
- Concentration of a substance in blood
- 1 dL = 100 mL (1 deciliter = 10th of a liter)
- µg/dL tells you: micrograms per 100 milliliters of blood
Common blood tests using µg/dL:
Blood Lead Level:
- Normal: <5 µg/dL
- Elevated: 5-10 µg/dL
- High: >10 µg/dL (concern)
- Toxic: >45 µg/dL
Blood Glucose (note: mg/dL, not µg/dL):
- Normal fasting: 70-100 mg/dL
- (This is milligrams, not micrograms!)
Iron/Ferritin: Sometimes reported in µg/dL Vitamin B12: Often ng/mL or pg/mL (nanograms/picograms)
Conversion:
- 1 µg/dL = 10 µg/L
- 1 µg/dL = 0.01 mg/L
- 1 µg/dL = 10 ng/mL
Clinical significance:
- Reference ranges vary by lab
- Always check lab's normal range
- Consult healthcare provider for interpretation
Note: µg/dL is different from µg/mL:
- 1 µg/dL = 0.01 µg/mL (100 times smaller)
