There are 10 lengths in 1/3 of a mile. This is not always the case, though. This answer is assuming the pool is a standard Olympic size, meaning one length is 50 metres. In pool jargon, a length is swimming down one way rather than down and back. In other words, if you want to know what a lap is you would go down to one end and come back to the starting point. This would be 100 metres. This would mean there are five laps in a 1/3 of a mile.

This calculation was derived by finding out how many metres are in a mile. There are 1609 (rounded) metres in a mile. Since there are 50 m in an Olympic pool that means there are 32 lengths because you divide 1609 by 50 to determine how many. A third of 32 is technically 10.333, which means 10 lengths in a pool for 1/3 of a mile.

If the pool is less than 50 m such as 25 m you would have to add more lengths to reach a 1/3 of a mile. In fact it would be double the lengths to reach a third of a mile. If the pool is even shorter you would need to add more lengths in order to reach 1/3 of a mile. Hotel pools tend to be much shorter than even half an Olympic sized pool. This means you may need to do more than 60 lengths in order to reach the goal of 1/3 of a mile.

When calculating out the amount you have to swim 10 lengths is actually a fairly small amount in numbers, but it is a great distance given the fact that you have reached 1/3 of a mile by going only 10 lengths.

Everyone here is wrong.... If there are 25 meters in 1 length of a pool, then a LAP would equal 50 meters. 586 meters divided by 25 meters is 23 POOL LENGTHS.... Or 11.5 round trip LAPS.
