At six foot two, the healthy range is about 144 to 194 pounds. The index behind that range was devised by Adolphe Quetelet, a Belgian statistician, in the 1830s. He was explicit that he was describing populations — his interest was in the characteristics of the average man as a statistical construct — and he made no c..

FULL SUMMARY
WHO BMI CATEGORIES
The height is already set to 6 ft 2 in, which is 188cm. Change it if that is not yours and everything below recalculates.
Enter a weight in whichever units suit you. The two systems give the same answer to about four significant figures — the imperial form uses a rounded conversion constant.
Read the range before the category. At this height it spans about 50 lb, and every weight inside it produces the same verdict from the measure.
Treat a reading near a boundary as near a boundary. Daily variation in weight and height covers a few tenths of a BMI point on its own.
At 6 ft 2 in — 74 inches, or 188cm — a BMI of 18.5 puts the lower bound at 65.4kg (144 lb) and a BMI of 24.9 puts the upper bound at 88.0kg (194 lb). The window is 22.6kg, or about 50 lb. One pound moves the number by 0.13 of a point, so it takes roughly 8 pounds to cross a whole one. On the WHO 2004 cut-offs for Asian populations the upper bound drops to 80.9kg (178 lb), 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 |
