# 키·몸무게 변환기: cm를 피트·인치로, kg을 스톤으로

> 정확히 2.54 cm인 인치를 사용하여 키를 cm와 피트·인치 사이에서 바꾸고 몸무게를 kg에서 파운드 또는 스톤·파운드로 환산합니다.

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.

### 180 cm and 75 kg

- 높이: 180 cm
- Weight: 75 kg
- **Height in feet and inches: 5 ft 11 in**
- **Height in inches: 70.87 in**
- **Weight in pounds: 165.3 lb**
- **Weight in stones and pounds: 11 st 11 lb**
- 검증 출처: 180 / 2.54 = 70.866 in → 71 in = 5 ft 11 in; 75 / 0.45359237 = 165.347 lb = 11 st 11.35 lb (Python fractions)

### 5 ft 11 in and 11 st 4 lb

- 높이: 5 ft 11 in
- Weight: 11 st 4 lb
- **높이: 180.3 cm**
- **Weight: 71.67 kg**
- **Height in feet and inches: 5 ft 11 in**
- 검증 출처: 71 × 2.54 = 180.34 cm; 158 lb × 0.45359237 = 71.66759446 kg (NIST HB 44)

### Rounding carries to the next foot and stone

- 높이: 182.5 cm
- Weight: 13 st 13.6 lb
- **Height in feet and inches: 6 ft 0 in**
- **Weight in stones and pounds: 14 st 0 lb**
- 검증 출처: 182.5 / 2.54 = 71.85 in → 72 in = 6 ft 0 in; 13 st 13.6 lb = 195.6 lb → 196 lb = 14 st 0 lb

### Exactly 5 feet

- 높이: 152.4 cm
- Weight: 75 kg
- **Height in feet and inches: 5 ft 0 in**
- **Height in inches: 60.00 in**
- 검증 출처: 152.4 / 2.54 = 60 in exactly

## 자주 묻는 질문

### 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.

### 피트와 인치를 센티미터로 어떻게 환산하나요?

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.

### “키·몸무게 변환기: cm를 피트·인치로, kg을 스톤으로”의 정확도는 어느 정도인가요?

정확도는 입력값과 계산 방법의 가정에 따라 달라집니다. 십진 연산은 유효숫자 50자리를 사용하지만, 추정값·수치해석 방법·원본 데이터의 정밀도는 더 낮을 수 있습니다. 표시값을 반올림해도 이러한 한계는 사라지지 않습니다. 독립적인 출처의 풀이와 대조한 계산 예시: 4. 예를 들어 “180 cm and 75 kg”은 180 / 2.54 = 70.866 in → 71 in = 5 ft 11 in; 75 / 0.45359237 = 165.347 lb = 11 st 11.35 lb (Python fractions)와 대조해 확인합니다.
