USMS time converter — SCY, SCM, LCM

Convert any swim time between Short Course Yards (SCY, 25-yard pool), Short Course Meters (SCM, 25-meter pool), and Long Course Meters (LCM, 50-meter pool). Openlane applies the conversion factors published by U.S. Masters Swimming so the converted time is directly comparable to USMS rankings and standards in the target course.

You can enter a time manually or, if you sign in and track a swimmer, pull the swimmer’s personal bests so every event converts in one pass. Converted times round to the nearest hundredth, matching how USMS reports meet results.
