Step by step
- 1Enter weight in kilograms in column A (header: Weight_kg) and height in meters in column B (header: Height_m).
- 2In column C, type the formula =A2/(B2^2) to get the BMI value — format the cell to 1 decimal place.
- 3In column D, add a category label: =IF(C2<18.5,"Underweight",IF(C2<25,"Normal",IF(C2<30,"Overweight","Obese"))).
- 4If your data uses pounds and inches, convert first: weight_kg = pounds * 0.453592, height_m = inches * 0.0254.
Tips
- Use named ranges (e.g., 'weight_kg' and 'height_m') to make the formula =weight_kg/(height_m^2) self-documenting for health or fitness trackers.
