From weighing luggage to following an overseas recipe or tracking body weight, converting between metric and imperial mass units is a common task. This converter covers every everyday unit at once.
Mass vs weight
In everyday language we say 'weight', but these units really measure mass — the amount of matter in an object. On Earth the distinction rarely matters for conversions, so kilograms and pounds are treated as directly interchangeable here.
The anchor conversion
The pound is defined as exactly 453.59237 grams. Every metric-to-imperial mass conversion derives from that definition, which keeps this converter's results exact rather than rounded approximations.
Frequently asked questions
One kilogram equals about 2.20462 pounds. So 70 kg is roughly 154.3 lb.
Divide the number of grams by 28.3495, since one ounce is about 28.35 grams. For example, 100 g ≈ 3.53 oz.
One stone equals 14 pounds, or about 6.35 kilograms. It's still commonly used for body weight in the UK and Ireland.
