One pound is defined as exactly 0.45359237 kilograms, so to convert kilograms to pounds you divide by that figure — or equivalently multiply by 2.20462. For 55 kg: 55 × 2.20462 = 121.25 lb.
For a rough mental conversion, double the kilogram figure and add ten percent: 55 × 2 = 110, plus 11 gives about 121 lb. That is within a fraction of a pound of the exact answer.
In stones, 9 stone is 57.15 kg, so 55 kg is 2.15 kg under that mark. UK and Irish scales usually display the stone figure and the leftover pounds separately rather than as a decimal.
This is the range where the stone matters most. UK and Irish scales and medical notes still record body weight in stones and pounds rather than in kilograms or plain pounds, so a figure here typically needs converting twice — first into pounds, then again into stones plus the leftover pounds.
