How much water does an Olympic sized swimming pool hold
www.patagoniaalliance.orgHow much water does an Olympic sized swimming pool hold? 2,500,000 litres or 2.5 megalitres of water. Olympic size pools measure: 50 metres long, 25 metres wide, and a minimum of 2 metres deep. (25m x 50m x 2m = 2,500m3; 1L = 0.001m3 so 2,500 x 1000 = 2,500,000L) 660,430 gallons of water. 50 meters = 164.041995 feet (a) 25 meters = 82.0209975 ...
