Convert between common metric and imperial units for length, mass, and volume.
Convert many values at once using your current From and To unit selection.
The converter reads the first column as numeric values and ignores non-numeric header rows.
Unit conversion multiplies the source value by a constant conversion factor: x_target = x_source x c_source_to_target. A reliable approach is to convert to a base unit first (meter for length, kilogram for mass, liter for volume), then convert from the base unit to the target unit.
Using a base unit makes it easy to convert between many different units without needing a direct factor for every possible pair. The calculator converts From unit to the base unit, then from the base unit to the To unit.
Examples include 1 ft approx 0.3048 m, 1 lb approx 0.4536 kg, and 1 US gal approx 3.785 L. The converter applies fixed factors consistently in both directions by using the reciprocal when needed.
Yes, as long as both units are available within the selected quantity type, you can choose them as the From unit and To unit. The conversion works in either direction by swapping the unit selections.
