1 US gallon = 0.133680556 feet^3
1 US gallon = 0.133680556 Cubic Feet (ft3); and 1 day = 24 hours = 1,440 Minutes. Math equation for conversion where "x=number of gallons per day" is: (x / 1440) x 0.133680556 Example: If x=30 (gallons per day), then: 0.208333 x 0.133680556 = 2.785 ft3 per Minute.
There are 7.48 gallons per cubic foot of interior space. You have to calculate the volume, in cubic feet, and then multiply that result times 7.48.
For US gallons, use this equation: gallons per minute x 8.020833333 = cubic feet per hour750 gallons/minute x 8.020833333 = about 6,015.625 cubic feet per hour
Cubic feet per hour x 7.48 = gallons per hour
880.57 US gallons per minute
> Best work with cubic feet, first calculate the volume of the tank in cubic feet: = Length * width * height (all dimensions in feet) Then : For US gallons, multiply volume (cubic feet) by 7.4805 For UK gallons, multiply volume (cubic feet) by 6.2288
499.39 gallons per 340 feet.
1 million gallons per day equates to about 0.001522472 cubic feet per second.
Pool capacity in gallons divided by fill time in hours equals fill rate in gallons per hour (gal / hr = gal/hr).
To calculate the gallons you also need the average depth. Then you take lenth X width X average depth = cubic feet of water. cubic feet of water X 7.48 {gallons per cubic foot} = total gallons.
20 US gallons per minute = 2.674 cubic feet per minute.
