Kg to Lbs Converter

About Weight Converter

Converts a weight between metric units (milligrams, grams, kilograms, tonnes) and imperial and US ones (ounces, pounds, stone, short and long tons). Every unit is shown at once from a single value.

The pound is defined as exactly 0.45359237 kg, and every other imperial unit is built from it, so the conversions are exact. The two kinds of ton are the ones that catch people out: a US short ton is 2,000 lb, a UK long ton 2,240 lb, and a metric tonne 1,000 kg sits between them.

Where it helps

• Metric, imperial and both kinds of ton side by side from one value.
• Exact definitions, so kilograms to pounds and back gives the number you started with.
• Stone is included, which most converters leave out and UK readers need.
• Works for anything from milligrams of medicine to tonnes of freight.

Limits

• Stone and pounds are shown as separate decimals, not as a combined 11 st 2 lb.
• Troy ounces, used for precious metals, are different from these ounces and are not included.
• Cooking measures by volume, such as cups, depend on the ingredient and cannot be converted here.
