All unit families
- Weight / Massmg · g · kg · t · oz · lb · stThe kilogram is the base unit, and until 2019 it was the last one still defined by a physical object: a platinum-iridium cylinder kept near Paris. It is now defined through the Planck constant, so it can be reproduced in any properly equipped laboratory.
- Temperature°C · °F · KTemperature is the one family here that is not a multiplication. Celsius and Fahrenheit have different zero points as well as different step sizes, so you need the formula: °F = °C × 9/5 + 32.
- Volumeml · l · m³ · gal · pt · fl oz · cupThis is the family where the same word means two different amounts. American and British measures share their names but not their sizes, and a recipe that ignores the difference will not work.
- Aream² · km² · ha · ft² · acAreas are where a linear conversion quietly goes wrong. One metre is 3.28 feet, but one square metre is 10.76 square feet — the factor is squared. Converting the sides and forgetting the square is the single most common mistake in this family.
- Speedkm/h · mph · m/s · knFour units, four different worlds. Kilometres per hour on European roads, miles per hour in the US and UK, metres per second in physics and weather bulletins, knots at sea and in the air.
- Times · min · h · d · wk · mo · yrSeconds, minutes, hours, days and weeks convert exactly. Months and years do not, and no converter can make them.
- Digital storagebit · B · KB · MB · GB · TBDigital storage has two conflicting definitions of the same prefixes, and almost every confusion about file sizes comes from that.
