1. The math is mutiply 39.37 times 25 meters to covert to yards, then divide that number by 36 (27.3 yards equals 25 meters). 2. Divide 400 yards by 27.3. This will give you the answer to your question (14.6 laps or down and back 7.3 times).
since 1 meter is equal to 1.094 yards, then one lap (one direction) in a 25 meter pool is really 27.35 yards. So then 500 yards at 27.35 yards a lap, you would need to complete a little more than 18 and a quarter laps (18.2815 to be more accurate).
386.24 Laps
89.4 laps (approx).
It will take 64.4 lengths (32.2 laps) to equal one mile.
1 yard = 0.9144 meters 400 yards x 0.9144 meters = 365.76 365.76/25 = 14 laps
72 lengths or 36 laps in a 25 meter pool
One meter is about 39.37 inches or 1.094 yards.
1 yard = 0.9144 meters.
500 yards is 20 laps
2 miles is 8 laps of a standard 400 meter track.
5 yards = 4.572 meters
13.1234 yards (1.09361 yards per meter).
