In the YMCA Swimming Pool how many laps is 1 mile? It's actually not all that obvious - you'll have to ask what the length of your pool is. It's *probably* 25 yards, but that's not certain. At my gym, it's 25m.
In meters, 1500m is generally considered to be 1 mile. In yards, 1650yd is 1 mile. If one length of the pool (Shallow - Deep) is 25m, then 50m / lap, so 30 laps. If one length is 50m (Olympic length), then 15 laps.
If one length of the pool is 25 yards, then 33 laps. If one length is 50 yards (very rare), then 16 laps + 1 length.
Happy swimming! https://answers.yahoo.com/question/index?qid=20080716135754AAAQkvm
