The kg to lb formula
Converting kilograms to pounds takes one step: pounds = kilograms × 2.2046, because 1 kg equals exactly 2.2046 lb. So 70 kg works out to 70 × 2.2046 = 154.3 lb, and a 5 kg parcel is 5 × 2.2046 = 11.02 lb. To go the other way, divide by 2.2046 or multiply by 0.4536 (1 lb = 0.4536 kg). Need a quick estimate in your head? Double the kilograms and add 10% — that puts the multiplier at 2.2, within a hair of the true value.
Where you'll actually use it
Telling someone your weight abroad? 60 kg is about 132.3 lb and 80 kg is roughly 176.4 lb. Luggage trips people up: a US airline's 50 lb limit is 22.68 kg, so packing to the common 23 kg metric allowance actually lands at 50.7 lb — just over the line. Gym plates differ too. A 20 kg Olympic barbell is 44.1 lb, but the US standard bar is 45 lb (20.4 kg), so 'one bar' isn't the same weight on both sides of the Atlantic.
Rounding, ounces, and other gotchas
The most common slip is using 2.2 instead of 2.2046. The error is only about 0.2%, but at 100 kg that's 220 lb versus the correct 220.46 lb. Pounds are also split into ounces rather than decimals: since 1 lb = 16 oz, 154.3 lb is close to 154 lb 5 oz. If you deal with UK body weight, note that 1 stone = 14 lb = 6.35 kg. And unlike temperature, kg and lb share a zero point — the relationship is a straight multiplication, with nothing to add or subtract.
Frequently asked questions
How many pounds is 1 kg?
One kilogram is 2.2046 pounds. The fuller figure is 2.20462262 lb, but 2.2046 is precise enough for everyday use. Going the other way, 1 lb is about 0.4536 kg.
Why 2.2046 instead of just 2.2?
2.2 is fine for rough mental math, but the exact conversion factor is 2.2046. Using 2.2 makes results come out slightly low, and the gap grows with weight — 90 kg is 198 lb at 2.2 but 198.4 lb at 2.2046.
What is a US airline's 50 lb bag limit in kg?
50 lb equals 22.68 kg. If you pack to the 23 kg metric allowance common elsewhere, you'll hit 50.7 lb and edge past a 50 lb limit, so keep bags under about 22.6 kg for US domestic flights.
