How to use this calculator

  1. Enter swim distance in yards or meters (stay consistent).
  2. Enter elapsed minutes and seconds.
  3. Read pace per 100 and per 50.
  4. Pool length only affects split count, not pace math.

Results explained

Pace per 100 = elapsed × 100 / distance. SCY vs SCM is whatever unit you typed; there is no automatic conversion.

Quick reference: swim pace

100 in 1:30 is 1:30/100 and 0:45/50.

How the estimate is built

pace100 = elapsed_seconds × 100 / distance; pace50 = pace100 / 2.

Example scenario

100 in 1:30 → 1:30 /100.

FAQ

Should I enter yards or meters?

Use the same unit your pool is marked in for that set.

How is running pace different?

Running pages divide time by miles or km; swim pace is per 100 of pool units.

Does pool length change pace?

No. A 25 m pool vs 50 m pool does not change /100 math if distance is total meters swum.
