Calories Burned Swimming Calculator
Estimate kilocalories for a swim from MET, body weight, and minutes. Choose leisure, moderate, or vigorous effort in the water. Informational, not a stroke analysis.

How to estimate swimming calories
- Select kilograms or pounds.
- Enter body weight and time in the water.
- Pick leisure, moderate, or vigorous swimming.
- Read session kcal and the MET used.
- Use the general calories page for dry-land sports. Nothing is uploaded.
Swimming calorie estimate
Swim MET × kg × hours
| Moderate MET | 8.0 (default) |
|---|---|
| Leisure MET | 6.0 |
| Vigorous MET | 10.0 |
| Formula | kcal ≈ MET × body kg × hours |
| Inputs | Weight, minutes, swim intensity |
| Advice | Informational. Not a pool coaching plan. |
What swimming calories estimates
Pool and open-water sessions share the same MET × mass × time product. Intensity selects leisure, moderate, or vigorous swimming. Stroke type is not a separate field, so you map freestyle drills or hard sets into those three bands.
How swim calories are computed
kcal ≈ MET × body kg × hours. Leisure uses MET 6, moderate uses MET 8, vigorous uses MET 10. Rest at the wall still counts if you leave it inside the minutes you type.
Swim MET and related jobs
Entities include swim MET, water session duration, and kcal. Cross-training lists live on calories burned. Cycling days sit on biking calories. Daily energy sits on TDEE.
Use cases
Sketching burn for a masters workout versus an easy lap swim. Logging aqua days without a chest strap. Teaching how water intensity still uses the same MET product. Not a swim-meet fueling chart.
Default numbers
At 70 kg for 45 minutes at MET 8, hours = 0.75, so kcal ≈ 8 × 70 × 0.75 = 420. Leisure MET 6 for the same slot is about 315 kcal.
Limits
Water temperature, current, and technique efficiency are omitted. Watches that use stroke rate will disagree. Informational only. See the disclaimer. CZNull does not receive swim logs.
