Definition of Tonne
- Definition
- The tonne (t), also called the metric ton, is a metric unit of mass equal to one thousand kilograms. It is commonly used in industry, shipping, and science.
The tonne provides a convenient scale for large masses while remaining compatible with the SI system. - Exact factor
- 1 t = 1000 kg = 2204.6226218 lb
- Examples
- • 1.5 t = 1500 kg
• 2 t ≈ 4409.25 lb
Definition of Ounce
- Definition
- The ounce (oz) is a unit of mass equal to one sixteenth of a pound in the avoirdupois system. It is commonly used for food portions, postal items, and small packages.
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 Tonne
Facts & Uses
- Also called the metric ton, equal to exactly 1000 kilograms. Recognized as a non-SI unit accepted for use with the SI by the BIPM.
- Standard for industrial production (steel, cement, grain harvests), international shipping (cargo manifests, container weights), and environmental reporting (CO₂ emissions in tonnes).
- Used in vehicle weight ratings (a small car ≈ 1–1.5 t; a fully loaded semi-truck ≈ 40 t in the EU), mining, and agriculture.
- Distinct from the US short ton (2000 lb ≈ 907 kg) and the UK long ton (2240 lb ≈ 1016 kg) — confusion between the three is a common source of trade disputes.
Curiosities
- The international symbol is "t" (lowercase) — the uppercase T is reserved for the tesla (magnetic flux density), an entirely unrelated SI unit.
- Global annual CO₂ emissions are measured in billions of tonnes (Gt); a single transatlantic flight emits about 1 t of CO₂ per passenger.
- The blue whale, the largest animal ever known, weighs up to 180 tonnes — equivalent to about 30 African elephants.
- 1 t = exactly 1000 kg = 2204.62 lb ≈ 1.102 short tons ≈ 0.984 long tons.

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.
