Health calculators with an educational focus and more context
The health category was built to answer common calculation intent with more editorial context, sources and warnings. Instead of just printing a number, each page tries to explain what the calculation measures and where it fails.
That includes BMI, child BMI, BMR, TDEE, daily water, macros, ideal weight, target heart rate and body fat percentage.
