How It Works

The UK uses a mix of metric and imperial weight measurements. Metric (kilograms and grams) is standard in shops and packaging by law, but many people still think in stones and pounds for body weight. This converter handles kg, pounds (lb), stones (st) and ounces (oz).

One stone equals 14 pounds, and one pound equals 0.4536 kilograms. The converter handles all combinations and displays results in the format most commonly used in UK daily life — for example, body weight in stones and pounds and food in kilograms or grams.

Example: Converting 75 kg

75 kg = 165.35 lb
75 kg = 11 stone 11.35 lb
75 kg = 2,645.55 oz
