Glossary

Metric tonne (t)

A metric tonne is exactly 1,000 kg (1 t = 2,204.62 lb ≈ 1.1023 US short ton). It is the standard unit for cargo shipping, industrial bulk weights, vehicle gross weights in metric countries and CO₂ emission accounting. Do not confuse with the US short ton (907 kg) or the UK long ton (1,016 kg) — those are imperial units.

Kilogram (kg)

The kilogram is the SI base unit of mass, redefined in 2019 in terms of the Planck constant (h = 6.62607015×10⁻³⁴ J·s). One kilogram equals 1000 g, 2.20462 lb or 0.157 stone. It anchors all other metric mass units and is the standard for body weight, groceries, freight and scientific work in nearly every country.

Metric system (SI)

The metric system is a decimal system of measurement built around the kilogram for mass, the meter for length and the second for time, with multiples and submultiples expressed as powers of ten (milligram, gram, tonne). Adopted in France in 1799 and codified internationally as the International System of Units (SI) in 1960, it is now the official system in nearly every country and the standard in science.

Imperial / US Customary system

The imperial system is the historical English system of weights and measures whose mass units are the ounce, pound, stone and ton (16 oz = 1 lb, 14 lb = 1 stone, 2,000 lb = 1 US short ton). Codified by the British Weights and Measures Act of 1824 and aligned with US Customary by the 1959 international yard-and-pound agreement (1 lb = 0.45359237 kg exactly), it is still used in the United States and the United Kingdom for everyday weights.
