Ideal weight for women and men at 173 cm
BMI is the same for women and men, but ideal-body-weight formulas — used by doctors to dose some medicines — give separate figures. At 173 cm, they put a woman's ideal weight at about 62.8 kg – 64.2 kg and a man's at about 67.4 kg – 69.9 kg. Anywhere in the healthy BMI range above is still a healthy weight.
| Formula | Women | Men |
|---|---|---|
| Robinson (1983) | 62.8 kg | 67.4 kg |
| Miller (1983) | 64.1 kg | 67.6 kg |
| Devine (1974) | 64.2 kg | 68.7 kg |
| Hamwi (1964) | 63.3 kg | 69.9 kg |
173 cm in feet and inches
173 cm is 5′8.1″ — 68.1 inches in total, or about 5′8″ rounded to the nearest inch. To convert, divide centimetres by 2.54 to get inches, then divide by 12 for feet: 173 ÷ 2.54 = 68.1 in, which is 5 ft and 8.1 in. A healthy weight at this height is 55.4 kg–74.5 kg, or 122 lb–164 lb.
How BMI is worked out at 173 cm
Body mass index is weight in kilograms divided by height in metres squared. 173 cm is 1.73 m, and 1.73² is 2.9929, so at this height BMI = weight ÷ 2.9929. For example, 76 kg ÷ 2.9929 = 25.4. 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 (68.8 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 173 cm, keep your waist under 86.5 cm. To enter an exact weight in kg or lb with your height in cm or feet, use the BMI calculator.
