About Weight Converter

Weight Converter changes values between milligrams, grams, kilograms, tonnes, ounces, pounds, and stones.

Enter a value, select From and To units, and read the result. In everyday speech "weight" often means mass here - the converter uses standard mass conversion factors.

For commercial trade and legal for-trade scales, certified instruments matter more than a web calculator. Shipping carriers may round dimensional weight separately from mass.
