Definition of Slug

Definition
The slug is a unit of mass in the imperial gravitational system, primarily used in physics and engineering calculations involving force and acceleration.

It is defined so that one slug accelerated at 1 ft/s² requires one pound-force.
Exact factor
1 slug = 14.593903 kg
Examples
• 1 slug ≈ 32.17 lb
• 2 slug ≈ 29.19 kg

Definition of Ounce

The ounce remains prevalent in countries using imperial or US customary units.
Exact factor
1 oz = 28.349523125 g = 0.0625 lb
Examples
• 16 oz = 1 lb
• 8 oz ≈ 226.8 g

About the Ounce

Facts & Uses

  • Avoirdupois ounce equals 1/16 of a pound = exactly 28.349523125 grams (derived from the 1959 Agreement on the pound).
  • Standard unit for food portions (deli meats, cheese), postal letter weights (US 1st-class mail), and beverage servings (a 12 oz soda can).
  • Common in cooking for both dry and fluid ingredients in the US — though the fluid ounce (volume) and ounce (mass) are unrelated and frequently confused.
  • Used in boxing glove weights (8 oz / 10 oz / 12 oz), archery (arrow weight), and jewelry for non-precious metal items.

Curiosities

  • The troy ounce (used for gold, silver, platinum) is heavier: 1 troy oz ≈ 31.1035 g, vs. 28.35 g for avoirdupois — a ~10% difference that matters at bullion prices.
  • The symbol "oz" derives from the medieval Italian onza, in turn from the Latin uncia meaning "a twelfth part" (originally 1/12 of a Roman pound).
  • 16 oz (1 lb) of feathers and 16 oz (1 lb) of gold weigh the same in avoirdupois — but the gold would actually weigh more if measured in troy ounces, since 1 lb troy = 12 troy oz only.
  • 1 oz ≈ 28.35 g ≈ 437.5 grains.
