Weight Converter (Kg, Stone, Pounds & Ounces)

How do you convert kg to stone?

Multiply kilograms by 0.157473 to get stone, or divide by 6.35029 — a stone is 6.35029 kg, which is exactly 14 pounds. So 70 kg × 0.157473 = 11.02 stone, and 88.9 kg = 14.00 stone. Because a stone is heavier than a kilogram, the same weight is always a smaller number in stone than in kilograms. The converter above does this the instant you type, and also splits the result into whole stone and leftover pounds so you do not have to.

To read a weight as stone and pounds, take the whole-number part as your stone, then multiply the leftover decimal by 14 for the pounds. For example, 70 kg is 11.02 stone: the 11 is your stone, and 0.02 × 14 ≈ 0.3 lb, giving 11 st 0.3 lb. The stone-and-pounds field on the converter shows this split automatically.

Kg to stone and pounds — full conversion table

These are the kg-to-stone conversions people look up most, from 60 kg up to 100 kg. Every figure below is produced by the converter at the top of the page — type the kilograms value into the Kilograms field to reproduce any row exactly, including the stone-and-pounds split.

88.9 kg is the exact weight at which the scale reads a round 14 st 0.0 lb (196.0 lb), which is why "88.9 kg in stone" is such a frequently searched figure. The nearby 90 kg reads 14 st 2.4 lb, and 95 kg reads 14 st 13.4 lb — just short of 15 stone.

How do you convert stone to kg?

Multiply stone by 6.35029 to get kilograms; if you also have pounds, add lb × 0.453592. So 11 stone is 69.85 kg, and 11 st 6 lb is 72.57 kg (11 × 6.35029 + 6 × 0.453592). If you are starting from a stone-and-pounds reading, the easiest route is to turn it into total pounds first — stone × 14 + pounds — then multiply by 0.453592. For example, 11 st 6 lb is 160 lb, and 160 × 0.453592 = 72.57 kg.

Kilograms, stone, pounds and ounces explained

The kilogram (kg) is the SI base unit of mass and the unit the UK uses for most trade, food and medicine. The stone (st) is a British imperial unit of exactly 14 pounds (6.35029 kg), used almost solely in the UK and Ireland for personal body weight. The pound (lb) is 0.453592 kg and divides into 16 ounces (oz) of 28.3495 g each. Grams and milligrams sit below them on the metric side, and the metric tonne above at 1,000 kg.

Ounces are where imperial cooking measures live: 16 oz make a pound (453.6 g), which is why recipes often round a pound of flour to 450 g. If you are converting cups, pints and fluid ounces rather than dry weight, use the volume converter. For distances and heights, the length converter handles metres, feet and inches the same live way.

Why the UK still weighs in stone

The UK keeps the stone (14 lb) for personal weight out of long habit, even though it uses kilograms for almost everything else and prices food in metric. Bathroom scales, doctors' surgeries and slimming groups still quote stone and pounds, so most people in Britain know their weight that way first and the metric figure second. That split is exactly why "kg to stone" — and specific targets like 88.9 kg in stone — remain among the most-searched conversions in the country.

For a named worked example you can check against the tool: type 88.9 into the Kilograms field and the converter returns 14 stone, a stone-and-pounds readout of 14 st 0 lb, 195.99 lb, 3135.86 oz and 88,900 g — the same round 14 stone used throughout this page. Type 70 instead and it returns 11.02 stone, 11 st 0.3 lb and 154.32 lb, matching the table above.
