Metric Ton

The metric ton (also "tonne" in British English) equals 1000 kilograms exactly. It is the standard tonnage unit in international shipping, agriculture and industrial production. Do not confuse it with the US short ton (907 kg) or the British long ton (1016 kg).

Real-world: A mid-size car weighs about 1.5 t. A 20-ft shipping container holds up to 28 t. Global steel output is about 1,900 million tonnes per year.

The milligram equals one thousandth of a gram. It is the dosing unit for most oral medications. A standard paracetamol tablet contains 500 mg. The daily recommended intake of iron for adult men is 8 mg, for women 18 mg. Micrograms (µg) are used for even smaller quantities like vitamin D.

Real-world: A paracetamol tablet is 500 mg. Daily iron intake: 8 mg (men) / 18 mg (women). Aspirin for heart protection: 75–100 mg daily.
