Population averages from height alone — they ignore build, muscle and frame. Not medical advice.
How it works
Each formula starts from a base weight at 5 feet (60 inches) and adds a fixed amount per inch above that — for example Devine uses 50 kg + 2.3 kg/inch for men (45.5 + 2.3 for women). Robinson, Miller and Hamwi differ only in those constants, which is why they give a small range rather than one number. Height is converted to inches first; all maths runs locally.
