Keep your measurements consistent

Choose a measurement type, enter a non-negative value, then select the original and target units. Swap units to reverse the direction without changing the physical quantity.

1 in = 2.54 cm · 1 lb = 0.45359237 kg

Length supports mm, cm, m, inches and feet. Weight supports g, kg, lb and oz. Volume supports m³, litres and ft³. Fluid ounces and gallons are excluded to avoid regional ambiguity.

Understanding the result

Is an ounce a fluid ounce?

No. Here oz means an avoirdupois ounce of mass. It cannot be converted to volume without the material’s density.

How precise is the display?

Up to six decimal places, with scientific notation for tiny non-zero results. Internal conversion uses unrounded values.
