What is this?
The Weight Converter translates values between kilograms, grams, milligrams, pounds, ounces, stones, and metric tons. It is built for the conversions that recur in daily life: body weight between kg and lb, cooking between grams and ounces, shipping between kilograms and tons, and UK-style weights expressed in stones.
Internally the tool converts your input to kilograms, then to the requested unit, which keeps all pairs consistent. Exact anchors: 1 kilogram is 2.20462 pounds, 1 pound is 453.592 grams, 1 ounce is 28.3495 grams, and 1 stone is 6.35029 kilograms (14 pounds). Results carry six decimal places with trailing zeros trimmed, so 72 kg reads as 158.732832 lb rather than a rounded guess.
For body weight, remember which direction you are moving: multiplying kg by 2.205 gives lb, while dividing lb by 2.205 gives kg - the tool removes that mental bookkeeping entirely. For recipes, note that ounces here are weight (avoirdupois), not fluid ounces, which measure volume and belong in the Volume Converter.
Precision beyond about four decimals is rarely meaningful for cooking or body weight, but it matters for materials, shipping, and lab work - and the tool gives it either way. Everything converts locally on your device.
