Calculate swimming pace per 100m or 100yd from split times and distance. Convert between pace formats for pool and open water training plans.
Calculate daily calorie needs from BMR and activity level. Get TDEE targets for weight loss, maintenance, or muscle gain using the Mifflin-St Jeor method.
Calculate pool laps, lengths, and distance from swim count. Convert between 25m, 25yd, and 50m pools for accurate distance tracking.
Metabolic Equivalent of Task values range from 5.8 (light freestyle) to 11.0 (butterfly vigorous). Multiply MET by body mass and hours for total energy expenditure.
Calories = MET × Weight (kg) × Duration (hours)Different strokes engage different muscle groups at varying intensities. Butterfly and vigorous freestyle burn the most calories per minute.
Freestyle moderate: MET 8.3 | Breaststroke: MET 8.0 | Butterfly: MET 11.0Alternative approach divides total calories by swim duration for per-minute burn rate, useful for comparing stroke efficiency.
Cal/min ≈ (MET × Weight kg) ÷ 60Updated: July 2026
A 75 kg swimmer doing moderate freestyle for 45 minutes burns approximately 470 calories — comparable to a 5-mile run at easy pace.
Swimming 4× per week at 300 calories per session creates a 1200 calorie weekly deficit from swimming alone, supporting 0.15 kg/week fat loss.
Estimate 350 calories for a 30-minute race-pace swim to plan pre-bike nutrition and avoid bonking on the cycling segment.
Swimming calorie burn depends on stroke, intensity, body weight, and duration. Enter your weight, swim stroke, effort level, and time to estimate calories burned using validated MET values for recreational and competitive swimming.
