How this weight converter works
This calculator converts a weight or mass value from one unit into another by converting your input to grams first, then converting from grams into the target unit. For example, one pound equals 453.59237 grams and one stone equals 6,350.29318 grams — these are the internationally recognized conversion factors.
It supports both metric units (milligrams, grams, kilograms, metric tons) and imperial/US units (ounces, pounds, stone), making it useful for cooking, shipping, fitness tracking, and everyday comparisons.
