Understanding Swim Metrics
A CSS swim calculator helps swimmers of all levels analyze their performance using key metrics:
Pace per 100m: The time taken to swim 100 meters. This is the fundamental metric for comparing swim performances worldwide. Elite swimmers maintain paces under 1 minute, while beginners are typically between 2-3 minutes.
Speed: Measured in meters per second (m/s) or kilometers per hour (km/h). This metric shows your velocity through water. Competitive swimmers typically maintain speeds between 1.7-2.3 m/s.
Calories Burned: Calculated based on weight, distance, stroke efficiency, and time. Swimming is one of the most effective calorie-burning exercises, with rates 30% higher than running.
Swolf Index: Combines stroke count and time to measure swimming efficiency. Lower values indicate better efficiency. Competitive swimmers typically have Swolf scores between 60-80.
International Swim Standards
This CSS swim calculator uses globally recognized standards to provide accurate metrics:
| Performance Level | Pace per 100m (Male) | Pace per 100m (Female) | Typical Swolf |
|---|---|---|---|
| Elite International | < 0:58 | < 1:04 | 55-65 |
| National Competitor | 0:58 - 1:05 | 1:04 - 1:10 | 65-75 |
| Regional Competitor | 1:05 - 1:15 | 1:10 - 1:20 | 75-85 |
| Fitness Swimmer | 1:15 - 1:40 | 1:20 - 1:45 | 85-100 |
| Beginner | 1:40 - 2:30+ | 1:45 - 2:30+ | 100-130+ |
