Someone weighing 70 Kg or 154.3 lb bicycling at 12 mph (80 rpm) burns 297.5 calories in 30 minutes. This value is roughly equivalent to 0.09 pound or 1.36 ounces or 38.6 grams of mass (fat and/or muscle).

  • Doing this activity 3 times a week for 30 minutes will burn 1.02 pounds or 0.46 Kg a month.
  • Doing this activity 5 times a week for 30 minutes will burn 1.7 pounds or 0.77 Kg a month.

A person will loose 1.36 ounces or 38.6 grams and will burn 297.5 calories bicycling at 12 mph (80 rpm) for 30 minutes

How to calculate the burned calories or weight (mass) loss

The number of calories you burn depends on:

Multiply your body weight in kg by the MET (Metabolic equivalent) value by the time of activity, you'll get the approximate energy expent in Kcal according to the person's body weight. In this case, bicycling at 12 mph (80 rpm) at a MET value, burns Kcal/kg x body weight/h.

A 70 kg individual bicycling at 12 mph (80 rpm) for 30 minutes will burn the following:

(METs x 70 kg body weight) x (30 min/60 min) = 297.5 Kcal.

is the value in METs for bicycling at 12 mph (80 rpm).

To transform the value in calories into pounds just divide the value in calories by 3500. So,

297.5/3500 = 0.09 pound = 1.36 ounces = 38.6 grams of mass. We can't say that it is fat because it could be also muscle.
