What does cubic foot per second measure?

It measures volumetric flow rate representing one cubic foot of fluid passing a point every second, commonly used in hydrology and engineering.

Why convert cubic foot per second to US gallons per hour?

Converting helps express large flow rates in smaller, more familiar liquid gallon increments per hour, which is useful in fuel consumption and dosing applications.

Does this conversion account for fluid temperature or pressure?

No, the conversion assumes steady flow and does not take into account changes in fluid compressibility, temperature, or pressure.
