All unit families
- Lengthmm · cm · m · km · in · ft · yd · miAlmost the whole world measures length in metres. The exceptions are narrow but stubborn: the United States uses feet and inches for everyday distances, and the United Kingdom still posts road signs in miles while selling timber in millimetres.
- 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.
- 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.

Frequently asked questions
How do you convert knots to kilometers per hour?
To go from kn to km/h: multiply by 1.852 (1 kn = 1.852 km/h). Example: 3 kn = 5.555999999 km/h. The converter above runs the math live as you type.
How much is 12 knots in kilometers per hour?
12 kn equals 22.224 km/h. For other values, use the quick table or type your own number into the converter.
What are knots (kn)?
The knot is one nautical mile per hour (1.852 km/h), the speed unit of ships, aircraft and wind at sea — named after the knotted rope sailors once used to gauge speed. A 20-knot wind is about 37 km/h.
What is kilometers per hour (km/h)?
Kilometers per hour is the road-speed unit of most of the world: how many km you cover in one hour. Highway limits are typically 100-130 km/h; a sprinting human peaks around 37 km/h.
