What is a Ton (UK) and a Slug?
The UK Ton, also known as the Long Ton or Imperial Ton, is a unit of mass in the Imperial system. It is defined as 2,240 pounds, which is equivalent to 1,016.0469088 kilograms.
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.
Note: The Ton (UK) is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Slug belongs to the imperial/US customary system.
History of the Ton (UK) and Slug
The term "ton" originates from the "tun," a large cask used in the wine trade. The long ton was standardized in the British Weights and Measures Act of 1824 and was historically used in the UK and Commonwealth countries for trade and shipping.
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).
Common Uses for long tons and slugs
Explore the typical applications for both Ton (UK) (imperial/US) and Slug (imperial/US) to understand their common contexts.
Common Uses for long tons
- Historically used for shipping bulk commodities in the UK and Commonwealth.
- Sometimes still used for measuring ship displacement.
- Occasionally encountered in older engineering specifications or historical 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.
Frequently Asked Questions
Questions About Ton (UK) (long ton)
How many pounds are in a UK Ton (Long Ton)?
There are exactly 2,240 pounds (lb) in 1 UK Ton (long ton).
Is a UK Ton larger than a US Ton?
Yes, a UK Ton (2,240 lb) is larger than a US Ton (short ton, 2,000 lb).
How does the UK Ton compare to the metric ton?
A UK Ton (1,016.05 kg) is very close to, but slightly larger than, a metric ton (tonne, 1,000 kg).
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.
