Swim course converter (SCY / SCM / LCM)

Enter a time and convert it between short-course yards, short-course meters, and long-course meters — a quick estimate for planning and goal-setting.

Key takeaways

  • SCY (25-yard) and SCM (25-meter) pools have more turns, so times are generally faster than LCM (50-meter).
  • This tool is a planning estimate, not official meet seeding.
  • Official qualifying conversions use USA Swimming’s per-event factors and turn counts.
  • Great for goal-setting when your season switches course type.

Estimate for planning only. Official meet seeding uses USA Swimming's per-event conversion (stroke, distance, and turn count), so qualifying times may differ.

About this tool

Swimmers move between yard and meter pools across the season, and a time in one course does not equal the same time in another. This converter gives a fast, freestyle-centric estimate so you can set goals — but it is not a substitute for the official conversion meets use to seed qualifying times.

How it works

  1. 1

    Enter a time

    Type the time you swam (m:ss.xx).

  2. 2

    Pick the courses

    Choose the pool you swam it in and the pool you want to convert to.

  3. 3

    Read the estimate

    Use the result for planning — check official standards for qualifying.

Frequently asked

Why is my short-course time faster than long-course?

Short-course pools (25 yards or 25 meters) have more walls, and every turn gives a push-off and underwater that is faster than swimming. More turns means faster times for the same swimmer.

Is this the official USA Swimming conversion?

No. This is a quick, freestyle-centric estimate for planning. Official seeding and qualifying use USA Swimming’s per-event conversion factors and turn increments, which vary by stroke and distance.

Can I convert between yards and meters distances too?

This converts times between course types. For qualifying, always check the official time standards for your meet and event.
