Enter your breaststroke distance and body weight to calculate your calories burned doing breaststroke. A 150 lb person burns about 24.5 calories per 100 meters of steady breaststroke.
Breaststroke Calorie Formula
BC = BW_{kg} \times D_m \times FVariables:
- BC is calories burned.
- BWkg is body weight in kilograms.
- Dm is breaststroke distance in meters.
- F is the breaststroke factor. Basic mode uses 0.0036 for a steady pace. Advanced mode lets you choose 0.0030, 0.0036, 0.0045, or 0.0055 based on effort.
If you enter pounds, yards, kilometers, or miles, the calculator converts them automatically before applying the formula.
How to Calculate Breaststroke Calories
- Enter your total breaststroke distance.
- Enter your body weight.
- Use Basic mode for steady lap swimming, or switch to Advanced mode and choose your effort level.
- Convert body weight to kilograms and distance to meters.
- Multiply body weight, distance, and the breaststroke factor to get calories burned.
Example: A 150 lb swimmer covering 1,000 meters of steady breaststroke burns 244.94 calories.
