Basal Metabolic Rate (BMR) is the amount of energy (kcal) your body would use in a day to stay alive and to maintain your current weight. Your BMR is dependent upon your sex, weight, height and age.
bmrKilo can calculate your BMR using kilograms (kilos, kg) for your weight, and meters (m) for your height. Once your sex, and age are entered the App will calculate your sedentary, lightly active, moderately active, very active, or extra active lifestyle BMR values.
If you are looking for a free BMR calculator that can work in pounds, or stone and pounds for weight and feet and inches for height then you might like to try bmrPounds or bmrStone from MMISoftware.
Alternatively, if you are looking for a BMR calculator that can do Imperial (feet, inches, pounds, stone and pounds) and metric (kilos, kilograms, meters) BMI calculations then try bmrCal. (The calculator can also convert between the different units.)
MMISoftware also offers a calculator, bodyCal, that can calculate your body mass index (BMI) and BMR using Imperial or Metric values.
