What is a Slug and a Troy Ounce?
The slug is a unit of mass in the Foot-Pound-Second (FPS) system of units, primarily used in Imperial and US customary systems. It is defined as the mass that accelerates by 1 foot per second squared (1 ft/s²) when a force of one pound-force (lbf) is exerted on it. It's approximately 14.5939 kilograms.
The troy ounce (oz t) is a unit of mass traditionally used for precious metals (like gold, silver, platinum) and sometimes gemstones. It is defined as exactly 31.1034768 grams.
Note: The Slug is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Troy Ounce belongs to the imperial/US customary system.
History of the Slug and Troy Ounce
The term "slug" was coined by Arthur Mason Worthington around 1900. It was derived from the concept of inertia (sluggishness) and designed to simplify calculations in Newtonian mechanics (F=ma) when using imperial units of force (lbf) and acceleration (ft/s²).
The troy weight system likely originated in Troyes, France, a major trading town in the Middle Ages. It became a standard in England for precious metals and coinage. Unlike the more common avoirdupois ounce (approx. 28.35 g), the troy ounce persists in the precious metals market.
Common Uses for slugs and troy ounces
Explore the typical applications for both Slug (imperial/US) and Troy Ounce (imperial/US) to understand their common contexts.
Common Uses for slugs
- Engineering (primarily aerospace and dynamics): Used in calculations involving force, mass, and acceleration within the Imperial system.
- Physics Education: Sometimes used when teaching mechanics with Imperial units.
Common Uses for troy ounces
- Precious Metals: The standard unit for quoting prices and weighing gold, silver, and platinum bullion (bars, coins).
- Gemstones: Sometimes used, although carat is more common for individual stones.
Frequently Asked Questions
Questions About Slug (sl)
How is the slug defined?
It's defined by Newton's second law (F=ma). 1 slug = 1 lbf / (1 ft/s²).
How many pounds-mass are in a slug?
One slug is approximately equal to 32.174 pounds-mass (lbm). This value corresponds to the standard acceleration due to gravity (g) in ft/s².
Why is the slug unit used?
It simplifies calculations in the F=ma formula when using pounds-force (lbf) and feet/second² (ft/s²) for acceleration, avoiding the need for a gravitational constant (g) in the equation.
About Troy Ounce (oz t)
Is a troy ounce the same as a regular ounce?
No. A troy ounce (approx. 31.10 g) is heavier than an avoirdupois ounce (the common "ounce" used for food, etc., approx. 28.35 g).
How many troy ounces are in a troy pound?
There are 12 troy ounces in one troy pound (which is lighter than an avoirdupois pound).
How many grams are in a troy ounce?
There are exactly 31.1034768 grams in 1 troy ounce.
