Formula
Per 100 m = Time (min) × 100 ÷ 12-min distance (m)
A 25 m pool involves more turns than a 50 m pool, so times differ at equal fitness.

Frequently asked questions
Q. How is Swim Pace per 100 m calculated?
Per 100 m = Time (min) × 100 ÷ 12-min distance (m) — Swimmers describe speed as time per 100 m. Covering 1,000 m in 22 minutes is 2:12 per 100 m.
Q. Can you walk through an example?
With 12-min distance (m) 1,000, Time (min) 22, the answer is Per 100 m 2.2min/km.
Q. What do I need to enter?
Enter 12-min distance (m), Time (min). The result recalculates as you type, and an empty box counts as zero.
Q. How much does the answer move if I change a number?
Changing only 12-min distance (m) moves the answer to 12-min distance (m) 500 → Per 100 m (min/km) 4.4 and 12-min distance (m) 2,000 → Per 100 m (min/km) 1.1. The table below lays out five steps.
Q. How are the numbers rounded?
Money is shown to the nearest whole unit, percentages to one decimal place and everything else to two. What you see is rounded; the calculation itself carries the unrounded value forward.
Q. Anything to watch out for?
A 25 m pool involves more turns than a 50 m pool, so times differ at equal fitness.
