Broca FormulaTo measure using the Broca formula, you just need to know your height. No other factors play a role.
Height in centimeters - 100 = Normal weightThe Broca formula, named after the inventor Paul Broca, a french army doctor, ist relatively easy and anyone can subtract 100 from their height in their head. Anyone who was born before 1975 will remember that this formula was commonly used in their childhood.
Normal weight - 10% = ideal weight
The ideal weight was added later. Paul Broca had to examine the military capability of young men. Obesity was not a problem then. His normal weight was therefore a lower limit. Anyone underneath it had problems with strenuous military service.
Height = 175 cmThis formula is considered outdated today, while the BMI isn’t any younger. They both come from the 19th century.
Normal weight = 175-100 = 75 kg
Ideal weight = 75 - 10% = 67,5 kg
