What Is the Divine Formula?
The Divine Formula, developed by Dr. B.J. Devine in 1974, is a standard calculation used by health professionals to estimate ideal body weight. It assumes a base weight for the first 5 feet (60 inches) and adds additional weight for every inch over 5 feet.
🔸 For Men:
Ideal Weight = 50 kg + 2.3 kg for every inch over 5 feet
🔸 For Women:
Ideal Weight = 45.5 kg + 2.3 kg for every inch over 5 feet
This method is particularly useful for calculating medication doses, assessing nutritional status, and planning health goals.
