Updated

Kilograms to Stone and pounds
16 st 0.9 lb
102 kg converts to the figure on the left, exactly. Nothing in it is an approximation.
Converting 102 kg
102 kilograms is 16 st 0.9 lb. A stone is 14 pounds and a kilogram is about 2.2046 pounds, so 102 kg is 224.9 lb, which is 16 whole stone with 0.9 lb left over.
Most converters stop at a decimal stone, which is not a unit anybody says out loud. 16 st 0.9 lb is the form you would use. In pounds alone it is 224.9 lb.
Between which whole stone
102 kg is 0.9 lb past 16 stone and 13.1 lb short of 17. 16 st exactly is 101.6 kg; 17 st is 108 kg. If you weigh yourself in stone, those are the two numbers either side of you.
What 102 kg means at different heights
At none of the heights below does 102 kg fall inside the range the NHS calls a healthy weight. It reads as obese (class 3) at 5 ft 0 in and overweight at 6 ft 2 in, a BMI of 43.9 down to 28.9.
| Height | BMI | NHS category | From healthy range |
|---|---|---|---|
| 5 ft 0 in | 43.9 | Obese (class 3) | 44.1 kg over |
| 5 ft 2 in | 41.1 | Obese (class 3) | 40.2 kg over |
| 5 ft 4 in | 38.6 | Obese (class 2) | 36.1 kg over |
| 5 ft 6 in | 36.3 | Obese (class 2) | 32.0 kg over |
| 5 ft 8 in | 34.2 | Obese (class 1) | 27.6 kg over |
| 5 ft 10 in | 32.3 | Obese (class 1) | 23.2 kg over |
| 6 ft 0 in | 30.5 | Obese (class 1) | 18.6 kg over |
| 6 ft 2 in | 28.9 | Overweight | 13.9 kg over |
102 kg sits above the healthy range at every height here, by 13.9 kg at 6 ft 2 in rising to 44.1 kg at 5 ft 0 in. That last column is the gap to the top of the band, which is not the same as how much anyone should aim to lose.
Losing 5 to 20% of 102 kg
Weight-loss advice is usually quoted in percentages, which is hard to picture. From 102 kg, this is what each of those marks comes to.
| Reduction | Weight lost | New weight | In stone and pounds |
|---|---|---|---|
| 5% | 5.1 kg | 96.9 kg | 15 st 3.6 lb |
| 10% | 10.2 kg | 91.8 kg | 14 st 6.4 lb |
| 15% | 15.3 kg | 86.7 kg | 13 st 9.1 lb |
| 20% | 20.4 kg | 81.6 kg | 12 st 11.9 lb |
The weight loss calculator estimates how long reaching one of those could take at a safe pace, and the weight loss percentage calculator works the other way round, turning weight already lost into a percentage.
BMI is a screening measure, not a diagnosis, and it says nothing on its own about how healthy you are. It does not know how much of you is muscle, and the thresholds are lower for some family backgrounds. What your BMI does and does not say.
The values either side
Scales rarely land on a whole number, and the one you want is often a kilogram either way.
