Convert kilograms to pounds instantly with a live calculator, a body weight reference chart for 40–120 kg, and a simple worked example.
The kilogram and the pound meet constantly because the world has two measurement systems living side by side. Someone moving from the UK, Europe, Australia, or Asia to the US walks into a doctor's office and their weight is suddenly in pounds. Gyms in the US load barbells in pounds, while the same plates in Europe are stamped in kilograms. Travelers weigh their luggage on a scale that reads kilos, then the airline's website states the limit in pounds.
Body weight is by far the most common use, which is why the chart below focuses on the adult range. Fitness trackers, calorie apps, and recipe calculators all flip between the two units depending on the country setting. The conversion factor is fixed, so this calculator gives the same answer every time, down to the decimal.

One kilogram = 2.20462 pounds. The pound is exactly defined as 0.45359237 kg, so the factor is exact.
70 × 2.20462 = 154.32 lb, usually said as 154 lb, or 11 stone in UK terms.
Divide pounds by 2.2 for a quick estimate. 154 ÷ 2.2 = 70 kg. For precision, divide by 2.20462.
A kilogram is officially a unit of mass. Weight is a force (newtons), but in everyday life people use kg and lb to mean weight, which works fine on Earth.
