The formula
pounds = kilograms × 2.2046226218The factor is exact in the other direction: since 1959 one pound has been defined as exactly 0.45359237 kilograms. Going from kilograms to pounds means dividing by that number, which does not come out to a terminating decimal, so 2.2046226218 is a rounding — accurate to about one part in ten billion, which is far beyond any scale you will ever stand on.
To go the other way, multiply by 0.45359237. See lbs to kg.

Body weight
Pounds alone is how body weight is quoted in the United States. In the UK and Ireland it is given in stones and pounds instead, so both are shown:
| Kilograms | Pounds | Stones and pounds |
|---|---|---|
| 50 kg | 110.2 lb | 7 st 12 lb |
| 60 kg | 132.3 lb | 9 st 6 lb |
| 70 kg | 154.3 lb | 11 st 0 lb |
| 75 kg | 165.3 lb | 11 st 11 lb |
| 80 kg | 176.4 lb | 12 st 8 lb |
| 90 kg | 198.4 lb | 14 st 2 lb |
| 100 kg | 220.5 lb | 15 st 10 lb |
To get stones from pounds, divide by 14. The whole number is the stones and the remainder is the pounds. See stone to kg.
Baggage allowances
Airline limits are the most common reason to convert a weight in a hurry, and the numbers are deliberately round in one system and awkward in the other:
| Allowance | Metric | Imperial |
|---|---|---|
| Standard international checked bag | 23 kg | 50.7 lb |
| US domestic checked bag | 22.7 kg | 50 lb |
| Heavier premium allowance | 32 kg | 70.5 lb |
| Typical cabin bag | 7 kg | 15.4 lb |
| Typical cabin bag (US) | 10 kg | 22 lb |
A 23 kg allowance and a 50 lb allowance are not the same limit. 23 kg is 50.7 lb, so a bag packed to exactly 50 lb clears both, and a bag packed to exactly 23 kg is 0.7 lb over a US domestic limit.
Estimating in your head
Double it, then add 10%. 70 kg doubles to 140, plus 14 is 154 lb — the true answer is 154.3 lb. The method is accurate to about 0.2% across the whole range of body weights, which is closer than most bathroom scales.
