Key Takeaways
- • SCY (25 yd), SCM (25 m), LCM (50 m)—three pool sizes.
- • SCY→SCM ×1.11, SCM→LCM ×1.025. Factors vary by event.
- • 50 m is Olympic standard. USA Swimming uses SCY for many meets.
- • More turns in short course = faster times; conversion adjusts.
Did You Know?
How Does Swim Time Conversion Work?
Pool Lengths
SCY 25 yd = 22.86 m. SCM 25 m. LCM 50 m. Shorter pool = more turns = faster times per 100. Conversion factors account for turn impact.
Conversion Factors
SCY→SCM ~1.11: SCY is shorter, so faster. SCM→LCM ~1.025: LCM has fewer turns. USA Swimming and FINA publish event-specific tables.
Accuracy
Factors are approximate. Sprints (50, 100) have more turn impact. Distance (1500) less. Use official conversion tables for exact comparisons.

Frequently Asked Questions
How do I convert swim times between pool sizes?
SCY→SCM ×1.11, SCY→LCM ×1.135, SCM→LCM ×1.025 (approximate; varies by event). 25 yd is shortest; 50 m is Olympic. Conversion factors account for turns and pool length.
What is SCY vs SCM vs LCM?
SCY = Short Course Yards (25 yd). SCM = Short Course Meters (25 m). LCM = Long Course Meters (50 m). Olympic pools are 50 m. SCY is common in US high school and college.
How accurate are conversion factors?
Factors vary by event. Sprints (50, 100) have more turns—SCY faster. Distance (1500) less turn impact. 1.11 SCY→SCM and 1.025 SCM→LCM are averages. USA Swimming and FINA publish event-specific factors.
What is the 1.11 SCY to SCM factor?
SCY is 25 yd = 22.86 m. Fewer meters per length in SCY, so more turns. 1.11 approximates the time adjustment: SCY times are faster per 100, so multiply by ~1.11 for SCM equivalent.
What is the 1.025 SCM to LCM factor?
SCM (25 m) has more turns than LCM (50 m). 1.025 is the approximate factor: SCM times are slightly faster, so multiply by ~1.025 for LCM equivalent. Varies by event.
Is 50 m the Olympic standard?
Yes. Olympic and World Championships use 50 m LCM. 25 m is common for winter/short course. 25 yd is US standard for many pools. FINA (World Aquatics) governs LCM competition.
