It covers metric units (centimetres, kilograms, litres), US and UK imperial units (inches, pounds, gallons) and everyday ones such as cups, stones, acres and kilowatt-hours.
Conversions use the official definitions — 1 inch is exactly 2.54 cm, 1 pound exactly 0.45359237 kg, 1 US gallon exactly 3.785411784 litres — and the page shows the factor, the formula, the value in every other unit and a chart of common values, so you can check or reuse the numbers.
