What is the fundamental difference between gallon (US)/second and cubic foot/second units?

Gallon (US)/second measures volumetric flow based on U.S. liquid gallons passing per second, whereas cubic foot/second is based on cubic feet per second, commonly used in engineering and hydrology.

Can I use this converter for accurate industrial pump specifications?

Yes, this tool provides standard unit conversions which can assist in pump design and specification by converting discharge rates consistently.

Why is cubic foot/second often preferred for large-scale water flow measurements?

Because cubic feet represent larger volume units, cubic foot/second simplifies expressing and calculating large discharge rates typical in hydrology and industrial applications.
