Weight Converter is a powerful free online tool available on ToolsMonk that helps you convert between kg, lbs, ounces, and more.

Weight Converter translates between metric and imperial weight units — grams, kilograms, tonnes, ounces, pounds, and stone — instantly and accurately, for cooking, shipping, fitness, and travel.
As with length, the usefulness lies in bridging two systems with awkward factors: metric scales cleanly by tens, while imperial mixes ounces, pounds, and stone with irregular relationships. The converter applies the precise factors (1 kg ≈ 2.20462 lb, 1 oz ≈ 28.35 g) so you get accurate results without remembering them.
It includes stone — 14 pounds, around 6.35 kg — because it's still standard for body weight in the UK and Ireland, so an 11-stone figure converts cleanly to pounds or kilograms. Strictly speaking mass and weight differ in physics, but in everyday Earth use they're interchangeable, which is how the tool treats them.
Conversion runs in your browser with nothing uploaded. Pair it with the Length, Temperature, and other ToolsMonk unit converters for complete everyday measurement reference.
Quick estimate: 1 kg ≈ 2.2 lb, and 1 stone = 14 lb (≈ 6.35 kg)
For cooking, grams↔ounces matters — 1 oz ≈ 28.35 g
Use the precise result for shipping where rounding could cross a pricing threshold
