1 cubic meters per hour approximates 0.59 cubic feet per minute. You can obtain the figure by converting a cubic meter to cubic feet, then divide the result, which is proximate 35.28, by 60 minutes.
1 meter equals 3.28 feet. Hence, a cubic meter is about 35.28 cubic feet (that is 3.28 to the third power). Consider that water flows through a certain surface with the volume of 1 cubic meter in an hour, which means 35.28 cubic feet per hour. Moreover, an hour consists of 60 minutes. Therefore, the volume of water flow in a minute is one to sixtieth of 35.28 cubic feet. Accordingly, the result is 0.59 cubic feet per minute.
