2 Ideal Weight Calculation Methods

Calculating The Ideal Body Weight with The BMI Method

BMI (Body Mass Index) is a health formula, in which a person's weight (W) (kg) divided by height (H) squared (m2).

BMI = (W) / [(H) * (H)]

For example: W = 45 kg and H = 165 cm, then

BMI = (45) / [(1.65) * (1.65)] = 16.5

Are you thin, normal or overwight? See the benchmark below:

BMI <18.5 = underweight

BMI 18.5 - 24 = normal

BMI 25-29 = overweight (overweight)

BMI> 30 = obesity

Calculate the Ideal Weight with Broca Method

Broca's formula was discovered by Pierre Paul Broca. As quoted from The Independent, this formula for calculating ideal body weight was discovered in 1871 by Dr. Pierre Paul Broca and popularized by Dr. BJ Devine in the 1970s.

Here's how to calculate the ideal body weight based on the Broca formula for women: (height - 100) - (15% x (height - 100)).

Example calculation:

If a woman has a height of 155 cm, her ideal weight: (155-100) - (15% x (155-100)) = 55-15 = 40. Then the ideal weight of a woman with a height of 155 cm is 40 kg.
And here's how to calculate the ideal body weight based on the Broca formula for men: (weight - 100) - (10% x (height -100)).
Example calculation:

If a man has a height of 180 cm, his ideal weight: (180-100) - (10% x (180-100)) = 80 - 8 = 72. Then the ideal weight of a man with a height of 180 cm is 72 kg.
However, keep in mind that calculating the ideal body weight by means of BMI and Broca is not always accurate because there are age factors and bone weight factors or body proportions.
