A height in centimetres becomes feet and inches by dividing by 2.54 cm per inch, rounding to the nearest inch and splitting into feet of 12 inches. A body weight in kilograms becomes pounds by dividing by 0.45359237 kg per pound, and stones and pounds by rounding to the nearest pound and splitting into stones of 14 pounds.

The default, 180 cm and 75 kg, gives 5 ft 11 in (70.87 in) and 165.3 lb, or 11 st 11 lb. Typing 5 ft 11 in or 11 st 4 lb straight into the fields works the other way.

Both factors are exact by the 1959 international yard and pound agreement, so the only approximation is the rounding to whole inches and pounds, which carries upward: 71.85 in shows as 6 ft 0 in, not 5 ft 12 in.

## الأسئلة

### How tall is 180 cm in feet and inches?

5 ft 11 in. 180 cm ÷ 2.54 = 70.87 in, which rounds to 71 in, and 71 in is 5 × 12 + 11. Six feet (72 in) is exactly 182.88 cm; with rounding to the nearest inch, any height from 181.61 cm (71.5 in) upward shows as 6 ft 0 in.

### كيف أحوّل الأقدام والبوصات إلى سنتيمترات؟

Turn the height into inches, then multiply by 2.54. 5 ft 11 in is 5 × 12 + 11 = 71 in, and 71 × 2.54 = 180.34 cm. The factor is exact: the 1959 international yard and pound agreement fixed the inch at 2.54 cm, so any error comes only from how many decimals you keep.

### How many pounds are in a stone?

14 pounds, so one stone is exactly 6.35029318 kg (14 × 0.45359237 kg). A weight of 11 st 4 lb is 158 lb, or 71.67 kg. The stone remains in customary use for body weight in the United Kingdom and Ireland, and for weigh-ins in boxing and horse racing there.

### What is 75 kg in stones and pounds?

11 st 11 lb. 75 kg ÷ 0.45359237 kg/lb = 165.35 lb, which rounds to 165 lb; 165 = 11 × 14 + 11, so the weight is 11 stone 11 pounds. In pounds alone it is 165.3 lb, and 12 stone (168 lb) would be 76.2 kg.
