Swimming Time Converter

Swimming time conversion uses performance prediction formulas based on physiological models. The calculator applies a swimming-specific exponent (typically 1.04) to predict times for different distances. For example, if you swim 100m in 1:30, it can predict your 200m time using established performance ratios.

25m pools typically produce faster times due to more turns and push-offs. Each turn provides a brief speed advantage. When converting between pool lengths, the calculator accounts for approximately 0.3 seconds per turn difference. A 100m time in a 25m pool might be 2-3 seconds faster than the same distance in a 50m pool.

Predictions are estimates based on proven swimming performance models and are typically accurate within 2-5% for trained swimmers. Accuracy depends on factors like training level, technique efficiency, and race strategy. Use these as training targets rather than exact predictions.

Yes, the calculator works for all swimming strokes (freestyle, backstroke, breaststroke, butterfly). However, stroke-specific factors may affect accuracy. Freestyle predictions tend to be most accurate due to more available data, while stroke specialists may see slight variations.

The calculator supports conversions between common competitive distances: 50m, 100m, 200m, 400m, 800m, and 1500m. It works best for distances within the same energy system (sprint to sprint, distance to distance) but can estimate across different race categories with reasonable accuracy.
