4 lenghts
It depends on the size of the swimming pools. If the pool is small, you need to swim many laps to get to 1/4 mile. 1/4 mile is 440 yards.
On an outdoor track 4 laps equal one mile. In a swimming pool, a swimming mile is 33 laps down and back, a real mile is 36 laps down and back.
22 laps in a 25 yard pool is equal to 1/3 mile. In competitive swimming, 66 laps or 1650 yds. is what is considered a mile. If swimming a 50 meter pool, 1,500 meters or 30 laps is a mile.
1/2 mile
64 lengths is a little less than a mile. 65 lengths would put you over.
1 mile = 1609.3412 metres 1609.3412 / 25 = 64.4 lengths (rounded to the nearest tenth)
1650 yards... it is also a long distance event in swimming.
As a lifelong swimmer, I've always thought of running to equal approximately 1/4 the workout of swimming, distance and time wise. A decent swimmer can swim 100 yards in about a minute at a sprint and a decent runner can sprint about 400 yards in about a minute. One mile is 1600 meters which equals 64 lengths (technically, a length is one way and a lap is down and back although most people use lap to mean just one way also) in a 25 meter pool. 400 meters swimming is 16 lengths= 1/4 miles swam which is the approximate equivalent to 1 mile run.
1 Nautical mile is = 1852m Swim 124 times
In an Olympic sized pool at 164ft, swimming from one side to the other side would be about .05km. So, you would have to swim to the opposite side of the pool 30 times to swim 1.5k.Assuming that 164ft is the pool size and one lap is considered swimming to the opposite side of the pool.If you're in a normal sized pool, you would need to swim 60 lengths.
About 64 laps. 25 meters is 82.021 feet. There are 5280 feet in a mile. 5280/82.021= 64.37
