What is a Kilogram and a Carat?
The kilogram is the base unit of mass in the International System of Units (SI). It is defined based on the fixed numerical value of the Planck constant.
The carat is a unit of mass used for measuring gemstones and pearls. It is defined as exactly 200 milligrams (0.2 grams).
Note: The Kilogram is part of the metric (SI) system, primarily used globally in science and trade. The Carat belongs to the imperial/US customary system.
History of the Kilogram and Carat
Originally defined as the mass of one liter of water. Later, it was represented by the International Prototype of the Kilogram (IPK), a platinum-iridium cylinder. In 2019, the definition was changed to be based on fundamental physical constants.
The term "carat" comes from the carob seed ("keration" in Greek), which was historically used as a standard for weighing small quantities due to its perceived uniform weight. The metric carat of 200 mg was adopted internationally in 1907.
Common Uses for kilograms and carats
Explore the typical applications for both Kilogram (metric) and Carat (imperial/US) to understand their common contexts.
Common Uses for kilograms
- Global Standard: The primary unit for mass in science (physics, chemistry), engineering calculations, and international trade (e.g., commodity pricing).
- Body Weight: Widely used worldwide (outside the US/UK primarily) for measuring human body weight for health and fitness tracking.
- Food & Groceries: Used for selling and labeling larger quantities of food items like rice, flour, sugar, and some produce in metric countries.
- Shipping & Logistics: Standard unit for calculating weights of packages and freight internationally.
- Everyday Objects: Measuring the mass of common items like furniture, electronics, or luggage.
Common Uses for carats
- Jewelry Industry: The primary unit for weighing diamonds and other precious gemstones.
- Pearls: Used for weighing pearls.
- Note: This is distinct from "karat," which measures the purity of gold.
Frequently Asked Questions
Questions About Kilogram (kg)
What is the base unit of mass in the SI system?
The kilogram (kg) is the base unit of mass in the International System of Units (SI).
Is the kilogram used worldwide?
Yes, it's the global standard for science, engineering, and international trade, and widely used for everyday measurements in most countries.
How was the kilogram originally defined?
It was initially defined as the mass of one liter of water, later represented by a physical artifact (the IPK), and is now based on the Planck constant.
About Carat (ct)
How many milligrams are in a carat?
There are exactly 200 milligrams (mg) in 1 carat (ct).
How many grams are in a carat?
There are 0.2 grams (g) in 1 carat (ct).
Is carat the same as karat?
No. Carat (ct) measures mass (weight) for gemstones, while Karat (K or kt) measures the purity of gold (e.g., 24K gold is pure gold).
