Basal Metabolic Rate Calculator
❤️ The human body. Use the Basal metabolic rate (Mifflin–St Jeor, male) formula to find bmr, mass, height, age: pick the value you want, type the others, and the answer updates as you go.
m in kg, h in cm, a = age in years. For females use −161 instead of +5.
Pick the ○ next to the value you want to find, fill in the others, and it solves as you type.
What each letter means
| Quantity | Unit |
|---|---|
| BMR | kcal/day |
| Mass | kg |
| Height | cm |
| Age | years |
Worked example
Find the bmr when Mass = 70 kg, Height = 176 cm, Age = 25 years.
Using BMR = 10m + 6.25h - 5a + 5: BMR = 1680 kcal/day.
Frequently asked questions
What is the formula for Basal metabolic rate (Mifflin–St Jeor, male)?
BMR = 10m + 6.25h - 5a + 5. m in kg, h in cm, a = age in years. For females use −161 instead of +5.
What do the letters stand for, and what units are used?
BMR in kcal/day, Mass in kg, Height in cm, Age in years.
How do you calculate bmr?
Put the values into BMR = 10m + 6.25h - 5a + 5. For example, with Mass = 70 kg, Height = 176 cm, Age = 25 years, bmr = 1680 kcal/day.
Can I solve for a different value?
Yes. In the calculator above, pick the circle next to any value (bmr, mass, height, age) and fill in the others: it rearranges the formula for you.
