Preparing your file
- A header row is required. Name the columns "height" and "weight". A column with "name" or "id" in its header is copied to the results.
- Choose the units your file uses: centimeters and kilograms, or inches and pounds. Convert feet and inches to total inches first (feet × 12 + inches).
- Commas, tabs or semicolons all work as separators, so you can paste straight from a spreadsheet.
- Rows that look wrong (missing values, impossible heights) are flagged so you can check them.
Example:
name,height,weight
Alex,170,65
Sam,182,88
Who it's for
School nurses, coaches, clinic staff, researchers and workplace wellness teams who need BMI for a group. Results use adult categories, which apply from age 20.1 For anyone under 20, use BMI-for-age percentiles instead.
