14 stone is 88.9 kg. Below: how that is worked out, and what it means at your height.
Updated
st lb = kg
Displayed values are rounded for readability, but the arithmetic uses the full precision of the internationally defined factors, a pound is exactly 0.45359237 kg and a stone is exactly 14 pounds, so converting back and forth will not drift.
Stone and pounds to Kilograms
88.9 kg
14 st 0 lb converts to the figure on the left, exactly. Nothing in it is an approximation.
Converting 14 st
14 stone is 88.9 kg. A stone is exactly 14 pounds and a pound is exactly 0.45359237 kg, so 14 st is 196 lb, and 196 lb is 88.9 kg.
The halves either side
Scales and people rarely stop at whole stone. 13 st 7 lb is 85.7 kg and 14 st 7 lb is 92.1 kg, so a half stone either side of 14 st spans 85.7 to 92.1 kg.

Losing 5 to 20% of 14 stone
Weight-loss advice is usually quoted in percentages, which is hard to picture. From 14 stone, this is what each of those marks comes to.
| Reduction | Weight lost | New weight | In stone and pounds |
|---|---|---|---|
| 5% | 4.4 kg | 84.5 kg | 13 st 4.2 lb |
| 10% | 8.9 kg | 80 kg | 12 st 8.4 lb |
| 15% | 13.3 kg | 75.6 kg | 11 st 12.6 lb |
| 20% | 17.8 kg | 71.1 kg | 11 st 2.8 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
Very few people are a whole number of stone, and the one you want is usually next door.
For the conversion in the other direction, see kg to stone, or stone to pounds for the same weight in pounds alone. The BMI calculator takes your own height rather than the eight above.
