About this tool.
Different countries and industries use different units, and a recipe, a shipping label or a science homework question rarely uses the one you know. This converter covers the everyday ones: length from millimetres to miles, weight from milligrams to tonnes, and temperature in Celsius, Fahrenheit and Kelvin.
Length and weight are converted by first turning the value into a base unit and then into the target unit, which keeps results accurate. Temperature uses formulas instead of a simple multiplier because the scales start at different zero points.
Three steps, then you are done.
