An online BMR calculator metric and BMR imperial calculator tool to calculate Basal Metabolic Rate for adult. Basal Metabolic Rate (BMR) is defined as the amount of energy expended daily by humans and other animals at rest.
BMR (Basal Metabolic Rate) calculator is used to calculate the base rate calorie consumptions when you at rest. It represents the minimum amount of energy needed to maintain the body's normal metabolic activity, such as respiration, keeping heart beating, maintenance of body temperature (thermogenesis), and digestion. BMR doesn't include the calories you burn from normal daily activities or exercise. The energy consumed is sufficient only for the functioning of the vital organs such as the heart, lungs, nervous system, kidneys, liver, intestine, sex organs, muscles, and skin.Basal metabolic rate may comprise 50-70% of total daily energy expenditure (dailyenergy needs) of man. BMR is measured in kilocalories (kcal).
Gender / Sex
The Harris-Benedict equation (also called the Harris-Benedict principle) is a widely used method to calculate BMR.English Imperial BMR Formula (US Standard / UK Standard)
Women: BMR=655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years)
Men: BMR=66 + (6.23 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in year)Metric System BMR Formula
Women: BMR=655 + (9.6 x weight in kilos) + (1.8 x height in cm) – (4.7 x age in years)
Men: BMR=66 + (13.7 x weight in kilos) + (5 x height in cm) – (6.8 x age in years)
