At this pace
The formula
pace per 100 = time ÷ distance × 100
100 yd is exactly 91.44 m, so the same speed takes about 8.6% less time per 100 yd than per 100 m.
What to watch out for
Count lengths carefully: 25 m and 25 yd pools are easy to mix up, and a watch can miscount turns. The table simply scales your pace, and most swimmers will slow over longer distances than the one they swam.
