approximate the BMR for a 180-lb, sedentary man over a 24-hour period. formula: 1 calorie per hour for every kilogram (2.2 lbs) of body weight. sedentary: add 200 calories per day

180-lbs must be converted to kilograms, which is 180 divided by 2.2, equivalent to approximately 82 kilograms. over the course of 24 hours, the man will burn 2,168 calories, because 82 kilograms multiplied by 24 calories plus 200 additional calories is equal to 2,168 calories burned.
