About the Conversion Calculator
Whether you're following a recipe from another country, converting weights for shipping, or doing schoolwork, unit conversion comes up constantly. Pick a category, enter a value, and select the source and target units.
Length, weight, and volume use multiplicative factors against a base unit (meter, kilogram, liter). Temperature uses linear formulas because each scale has its own zero point.
