What is a Slug and a Pound?
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 pound (avoirdupois) is a unit of mass used in the imperial and US customary systems. It is defined as exactly 0.45359237 kilograms.
Note: The Slug is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Pound belongs to the imperial/US customary system.
History of the Slug and Pound
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).
Originates from the Roman 'libra'. The avoirdupois pound became the standard for commerce in England and was later adopted in the US.
Common Uses for slugs and pounds
Explore the typical applications for both Slug (imperial/US) and Pound (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 pounds
- Body Weight: The primary unit for measuring human body weight in the United States, United Kingdom, and Canada, commonly seen on personal scales.
- Food & Groceries (US/UK): Standard unit for selling and pricing produce (e.g., apples, potatoes by the pound), meat, cheese, and deli items. Recipe ingredients are often measured in pounds or ounces.
- General Weight: Used for everyday weight measurements in non-scientific contexts in the US/UK, such as package weight for domestic shipping or luggage weight.
- Specific Applications: Sometimes used in technical fields like measuring tire pressure (pounds per square inch, PSI - though PSI is pressure, not mass) or fishing line strength (lb-test).
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 Pound (lb)
What measurement system uses pounds?
The pound (lb) is a key unit in the imperial and US customary measurement systems.
Where is the pound commonly used?
Primarily in the United States, United Kingdom, and Canada for everyday measurements like body weight and groceries.
How many ounces are in a pound?
There are exactly 16 avoirdupois ounces (oz) in 1 avoirdupois pound (lb).
