What Is a Unit Converter?
A unit converter is a computational tool that translates a numerical value expressed in one unit of measurement into its mathematically equivalent value in another unit of the same physical quantity.
Behind every conversion is a precise conversion factor — the ratio between two units. Multiply by this factor and you instantly bridge measurement systems that evolved independently across civilisations.
