How To Calculate Your Basal Metabolic Rate
Basal Metabolic Rate is the energy required to maintain the body’s normal function, it is a measure of how much energy is used by someone who is at rest. To calculate your BMR we are going to use the Schofeild equation. This equation takes into account someone’s age, weight , it is very accurate for the average adult.

Schofeild Equation

MENS :


  • 10 - 17 years BMR = 17.7 x W + 657
  • 18 - 29 years BMR = 15.1 x W + 692
  • 30 - 59 years BMR = 11.5 x W + 873
  • 60 - 74 years BMR = 11.9 x W + 700

WOMENS :


  • 10 - 17 years BMR = 13.4 x W + 692
  • 18 - 29 years BMR = 14.8 x W + 487
  • 30 - 59 years BMR = 8.3 x W + 846
  • 60 - 74 years BMR = 9.2 x W + 687

Key: W = Body weight in kilograms

To calculate your weight from pounds into kilograms you have to divide by 2.2, for example if you weigh 140 pound you would divide 140 by 2.2 which would give you 63.6.

conversion table:


  • 100 pound ÷ 2.2 = 45.4kg
  • 110 pound ÷ 2.2 = 50kg
  • 120 pound ÷ 2.2 = 54.5kg
  • 130 pound ÷ 2.2 = 59kg
  • 140 pound ÷ 2.2 = 63.6kg
  • 150 pound ÷ 2.2 = 68.1kg
  • 160 pound ÷ 2.2 = 72.7kg
  • 170 pound ÷ 2.2 = 77.2kg
  • 180 pound ÷ 2.2 = 81.8kg
  • 190 pound ÷ 2.2 = 86.3kg
  • 200 pound ÷ 2.2 = 90.9kg
  • 210 pound ÷ 2.2 = 95.4kg
  • 220 pound ÷ 2.2 = 100kg

Here is an example of how to work out your Basal Metabolic Rate. Lets say you are a 24 year old 140 pound bodybuilder so we use the equation

18 - 29 years BMR = 15.1 x W + 692

So it would be

15.1 x 63.6 + 692 = 1,652 calories

BMR = 1,652
