What is a Slug and a Carat?
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 carat is a unit of mass used for measuring gemstones and pearls. It is defined as exactly 200 milligrams (0.2 grams).
Note: The Slug is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Carat belongs to the imperial/US customary system.
History of the Slug and Carat
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 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 slugs and carats
Explore the typical applications for both Slug (imperial/US) and Carat (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 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 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 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).
