What is BMR?
BMR is a measure of your energy requirement (in terms of calories)
BMR calculator gives the calories needed to perform your basic function at rest or at steady state.
It is also referred to as Resting Metabolic Rate (RMR) , or Metabolic Calorie Calculator
BMR is measured in units of Kilocalories or Kilo Joules
How to use BMR Calculator / RMR Calculator to find Calories Burnt
There are 2 equations that are commonly used to calculate BMR:
Mifflin-St Jeor Equation
Harris-Benedict Equation
Mifflin-St Jeor Equation : It is a revised equation for calculating resting energy requirement.
Mifflin-St Jeor Equation is estimated to be 5% more accurate. It provides Resting Metabolic Calorie.
Harris-Benedict Equation : A method used to estimate Basal Metabolic calorie
The Harris-Benedict and Mifflin-St Jeor formula provide an estimate of basic minimum calories needed and this is useful input for those into weight loss programs. It gives an estimate of how much calories to burn to reduce fat.
Also, the basal calorie value is an input to avoid getting into issues related to low RMR and Low BMR and ensure minimum calorie intake is maintained.
BMR Formula for Men by Mifflin-St Jeor Equation
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) + 5
BMR Formula for Women by Mifflin-St Jeor Equation
BMR = 10 x weight (kg) + 6.25 x height (cm) – 5 x age (years) – 161
BMR Formula for Men by Harris-Benedict Equation
BMR = 88.362 + (13.397 × weight in kg) + (4.799 × height in cm) - (5.677 × age in years)
BMR Formula for Women by Harris-Benedict Equation
BMR = 447.593 + (9.247 × weight in kg) + (3.098 × height in cm) - (4.330 × age in years)
Average BMR
Average basal metabolic rate for women is 1409 kcal per day (5900 kJ)
Average basal metabolic rate for men 1696 kcal per day(7100 kJ)

Frequently Asked Questions on BMR
BMR is basal metabolic rate. It is a measure of the calories needed by the body to perform its basal functions at complete resting state with no activity. Basal functions are digestion, circulation, breathing, sleeping and so on. It is measured in terms of kcal per day.

It is Resting Metabolic Rate. It is almost same as BMR. It is the calories needed at resting state but it involves normal movement like getting up, eating , bathing but no exercise as such. RMR is always slightly more than BMR.

BMR calculator is used to find your basal metabolic rate using height, weight and gender. BMR for men and BMR for women are different. BMR can be measured with tool and apparatus as well as can be roughly computed by standard formula. BMR is calculated using one of 2 equations - Harris-Benedict Equation or Mifflin - St Jeor Equation. Mifflin - St Jeor Formula is for computing RMR while Harris Benedict formula computes BMR.
