At 85kg the healthy heights run from 185 to 214cm — which for most people means this weight reads as above the healthy range. That is where the measure's best-known weakness matters. BMI cannot tell what weight is made of, and 85kg on a trained body at 180cm carrying single-figure body fat produces the same 26.2 as 85..

FULL SUMMARY
WHO BMI CATEGORIES
The weight is already set to 85kg, which is about 187 pounds. Enter your height and the BMI follows — until you do, the figure is undetermined.
Both unit systems are seeded, so switching between kilograms and pounds keeps the same weight rather than reverting to a default.
Read the band of heights rather than any single BMI. At 85kg the healthy band runs 185 to 214cm, and that band is what a weight actually determines.
A reading near a category boundary should be read as near a boundary. Most people vary by one to two kilograms across a day from food and fluid alone.
At 85kg — about 187 pounds — the BMI is undetermined until a height is supplied. At 150cm it is 37.8, at 175cm 27.8, and at 200cm 21.3: a spread of 16.5 points from one unchanged weight, which is wider than the entire healthy band. Inverting the formula gives what a weight can determine: 85kg sits inside the healthy BMI band for heights between 185cm and 214cm, a window 29cm wide, or roughly 6ft 1in to 7ft 0in. On the WHO 2004 cut-offs for South and East Asian populations the shortest suitable height rises to 193cm, because those thresholds lower the top of the BMI band while leaving 18.5 in place.
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 |
