Swim Time Converter

SCY ⇄ SCM ⇄ LCM — event-aware and real-time.

Decimals

Formats: ss.hh, m:ss.hh, or h:mm:ss.hh

Advanced: Per-wall advantage (seconds)

Adjust to match your turns & underwater skills
SCY (25 yards)
0.55s
SCM (25 meters)
0.4s
LCM (50 meters)
0.25s

Model: remove wall gains from your source swim to estimate free-water speed, then reapply gains for the target course. Outputs are estimates.

How the Swim Time Converter Works

  1. We parse your source time and event to get distance and course.
  2. We estimate the number of walls (start + turns) from pool length and distance.
  3. We subtract a per-wall advantage (adjustable) to estimate your free-water speed (m/s).
  4. We project that speed to the target event and add the target course’s wall gains.

Because turns, push-offs, and underwater phases are highly individual, use the sliders to match your profile for better estimates.

Information & FAQs

How do you calculate swim time?
Time is a function of distance, pool length, and your pace between walls. Our model adjusts for start/turn advantages so you can compare SCY, SCM, and LCM more fairly.
Is the swimswam time converter accurate?
All public converters are estimates. Individual strengths (e.g., underwater dolphin, turns) can make you faster in short-course than long-course, or vice versa. Use the sliders to tune.
What is a good 2000 yard swim time?
It depends on experience. Fitness swimmers often aim for 30–40 minutes continuous; competitive swimmers may go well under that.
What is a good 1000m swim time?
Many aim for 18–25 minutes; competitive benchmarks vary by level and event focus.
