Ideal weight for women and men at 171 cm

| Formula | Women | Men |
|---|---|---|
| Robinson (1983) | 61.4 kg | 65.9 kg |
| Miller (1983) | 63.1 kg | 66.5 kg |

| Hamwi (1964) | 61.6 kg | 67.8 kg |
171 cm in feet and inches
171 cm is 5′7.3″ — 67.3 inches in total, or about 5′7″ rounded to the nearest inch. To convert, divide centimetres by 2.54 to get inches, then divide by 12 for feet: 171 ÷ 2.54 = 67.3 in, which is 5 ft and 7.3 in. A healthy weight at this height is 54.1 kg–72.8 kg, or 119 lb–161 lb.
How BMI is worked out at 171 cm
Body mass index is weight in kilograms divided by height in metres squared. 171 cm is 1.71 m, and 1.71² is 2.9241, so at this height BMI = weight ÷ 2.9241. For example, 75 kg ÷ 2.9241 = 25.6. The table above does this for every whole kilogram.
The categories are the World Health Organization's adult ranges. Some guidelines use lower cut-offs for people of South Asian, Chinese and other Asian backgrounds — overweight from a BMI of 23 (67.3 kg at this height) — because health risks rise at a lower BMI. BMI does not tell muscle from fat, so also check your waist-to-height ratio: at 171 cm, keep your waist under 85.5 cm. To enter an exact weight in kg or lb with your height in cm or feet, use the BMI calculator.
