Convert instantly between metric and imperial units for length, weight, temperature, volume, area, and speed — with a full reference table showing your value in every unit at once.
Each category is built around a base unit — meters for length, kilograms for weight, liters for volume, square meters for area, and meters per second for speed. Your input is first converted to that base unit, then converted again into the target unit, which keeps every conversion factor accurate and consistent.
Temperature is the one category that isn't a simple multiplication — Celsius, Fahrenheit, and Kelvin each need their own formula, which the calculator applies automatically. The reference table below the result shows your value converted into every unit in the category at once, so you can compare several units without recalculating.
