What Is a Weight Converter?

A weight converter is a tool that translates a mass measurement from one unit system to another — for example, metric (kilograms, grams) to imperial (pounds, ounces). Technically these are mass units, but in everyday use we call them weight. Our converter supports 9 common units including metric tons, US short tons, and UK long tons.
