Frequently Asked Questions
Are the calculators for beginners and elites?
Yes. The same tools work for age-group swimmers, college, and elite. Outputs scale to the time you enter.
How accurate are the numbers?
Formulas draw on large samples of elite racing and are updated over time. Your technique, pacing, and conditions still matter; treat results as high-quality guides, not guarantees.
SCY, SCM, and LCM — which should I use?
Use the course you train and race in. Convert with the Swim Time Converter when comparing across yards and meters.
Can I use these for open water or triathlon?
Yes. Pace, CSS, and speed tools are useful for pool prep and open-water pacing; always adjust for conditions and drafting.
What are World Aquatics (FINA) points?
A standard way to score a swim relative to world-class standards. Use the points calculator for entries, rankings, and progress checks.
