At 174cm the healthy range is 56.0 to 75.4kg. This page carries a small honest wrinkle. Switching the calculator to feet and inches gives 5 foot 9, which is 175.26cm — about a centimetre and a quarter taller than the height this page is about. So does 176cm, which rounds to the same 5 foot 9. The imperial system simp..

FULL SUMMARY
WHO BMI CATEGORIES
The height is already set to 174cm, which is about 5 ft 9 in. Change it if that is not yours and everything below recalculates.
Enter a weight in kilograms. Switching to imperial converts the height to the nearest inch, which is a coarser step — two adjacent even centimetre values can land on the same one.
Read the range before the category. At this height it spans 19.4kg, and every weight inside produces the same verdict.
Treat a reading near a boundary as near a boundary. One kilogram is 0.33 of a point here, and most people vary by more than that across a day.
At 174cm — 1.74m, or about 5 ft 9 in — a BMI of 18.5 puts the lower bound at 56.0kg and a BMI of 24.9 puts the upper bound at 75.4kg. The window is 19.4kg, or about 43 pounds. One kilogram moves the number by 0.33 of a point, so it takes roughly 3.0kg to cross a whole one. On the WHO 2004 cut-offs for South and East Asian populations the upper bound drops to 69.3kg, a reduction of 6.1kg, with the lower bound unchanged.
FORMULA REFERENCE TABLE
| Name | Formula | Description |
|---|---|---|
| BMI (Metric) | BMI = weight(kg) / height(m)² | Divide weight in kg by height in metres squared |
| BMI (Imperial) | BMI = 703 × weight(lbs) / height(in)² | Multiply weight in pounds by 703, divide by height in inches squared |
| Height in metres | h(m) = h(cm) / 100 | Convert centimetres to metres before squaring |
| BMI Prime | BMI Prime = BMI / 25 | Ratio of BMI to upper limit of normal (25). Values >1.00 indicate overweight |
| Ponderal Index | PI = weight(kg) / height(m)³ | More accurate than BMI for very tall or short individuals. Normal: 11–15 kg/m³ |
| Healthy weight | w = BMI × height(m)² | Rearranged BMI formula: weight(kg) for any target BMI at your height |
