  1. Know what the formulas are

    Devine (1974), Robinson (1983), Miller (1983) and Hamwi (1964) each give a base weight at 5 feet and add a fixed amount per inch above it, with separate numbers for men and women. They were built for drug dosing and insurance tables, so they differ by a few kilograms.

    Each formula: a base weight at 5 ft plus a fixed amount per inch, different for men and women.

  3. Enter sex and height

    Pick Male or Female and type the height in cm. For feet and inches switch Units to imperial; the results then show in pounds. Below 5 ft (152.4 cm) the formulas extrapolate, so treat those results as rough.

  4. Read the four formulas

    For a 170 cm man: Devine 65.9 kg, Robinson 65.2 kg, Miller 66 kg, Hamwi 66.7 kg. For a 160 cm woman: 52.4, 54.1, 57.2 and 52.1 kg. The spread is the answer; no single formula is right.

    170 cm man: Devine 65.9, Robinson 65.2, Miller 66, Hamwi 66.7 kg; BMI range 53.5–72 kg.
    170 cm man: Devine 65.9, Robinson 65.2, Miller 66, Hamwi 66.7 kg; BMI range 53.5–72 kg.

  5. Read the BMI range

    The last row is the weight that gives a BMI of 18.5 to 24.9: 53.5 to 72 kg at 170 cm. Muscle, frame and age shift what is healthy for you.
