Converters

Convert between kilograms, pounds, ounces and more

Weight converter takes a number, the unit it is in, and shows the same mass in every unit at once: milligrams, grams, kilograms, metric tons, ounces, pounds and stone. Anyone quoting shipping weights, package labels or training loads across metric and imperial markets reaches for it. Choose the starting unit in "From" (kilograms by default) and type the value. The avoirdupois pound is exactly 0.45359237 kg, and results are shown to ten significant digits.

Frequently asked questions

Can I convert pounds to kilograms?

Yes. Set From to Pounds (lb) and type the number: 150 lb is about 68.04 kg, in the kilograms line. The same works from ounces, stone, grams, milligrams or metric tons, and every other unit is listed at the same time.

How many ounces and pounds are in a kilogram?

One kilogram is 2.2046226 pounds or 35.273962 ounces. The tool uses the exact definitions, 1 lb = 0.45359237 kg and 1 oz = 28.349523125 g, so 10 kg shows 22.04622622 lb and 352.7396195 oz to ten significant digits.

Is stone included?

Yes. One stone is 14 pounds, 6.35029318 kg. It is listed with the other units, so you can enter a body weight in stone and read it in kilograms, or the reverse.

Is a ton the same as a metric ton?

Here a ton is a metric ton (tonne), 1000 kg. US short tons (2000 lb) and imperial long tons (2240 lb) are not included; convert those through pounds if you need them.
