What is a Slug and a Quintal?
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 quintal (q) is a historical unit of mass, typically defined as 100 units of either kilograms or pounds, depending on the context. The metric quintal is precisely 100 kilograms.
Note: The Slug is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Quintal belongs to the imperial/US customary system.
History of the Slug and Quintal
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 derives from Arabic ("qinṭār") and Latin ("centenarius" meaning "containing a hundred"). It was widely used across Europe and its colonies, but its value varied significantly by region (sometimes being 100 pounds, sometimes 100 kilograms, or other values). The metric quintal (100 kg) is the most common modern interpretation.
Common Uses for slugs and quintals
Explore the typical applications for both Slug (imperial/US) and Quintal (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 quintals
- Agriculture: Still used in some countries (e.g., India, Brazil, France) for trading grain, coffee, and other agricultural commodities, usually referring to the 100 kg metric quintal.
- Historical Context: Encountered in historical trade documents.
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 Quintal (q)
How many kilograms are in a metric quintal?
There are exactly 100 kilograms (kg) in 1 metric quintal (q).
How does a quintal relate to a metric ton?
One metric ton (tonne, t) is equal to 10 quintals (q), as 1 tonne = 1000 kg and 1 quintal = 100 kg.
Is a quintal always 100 kg?
Not historically. While the metric quintal is 100 kg, older definitions or regional variations could refer to 100 pounds or other amounts. Context is important.
