At 130kg the BMI is 42.4 at 175cm and 32.5 at two metres. Something worth noticing at these weights: a kilogram is worth the same fraction of a BMI point regardless of how heavy you are — one divided by height in metres squared, so 0.33 at 175cm. What changes is the proportion. One kilogram is 0.8% of 130kg and 1.4% o..

FULL SUMMARY
WHO BMI CATEGORIES
The weight is already set to 130kg, which is about 287 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 130kg the healthy band runs 228 to 265cm, 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 130kg — about 287 pounds — the BMI is undetermined until a height is supplied. At 150cm it is 57.8, at 175cm 42.4, and at 200cm 32.5: a spread of 25.3 points from one unchanged weight, which is wider than the entire healthy band. Inverting the formula gives what a weight can determine: 130kg sits inside the healthy BMI band for heights between 228cm and 265cm, a window 37cm wide, or roughly 7ft 6in to 8ft 8in. On the WHO 2004 cut-offs for South and East Asian populations the shortest suitable height rises to 238cm, 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 |
