What does gallon (US)/minute measure?

It measures volumetric flow rate as the number of U.S. liquid gallons passing a point each minute, primarily for liquids.

Where is cubic foot/minute commonly used?

It is used to quantify gas or air volumes flowing per minute, especially in HVAC systems, ventilation, and industrial applications.

Why must I be careful converting between these units?

Because gallon (US)/minute usually refers to liquid flow and cubic foot/minute to gas flow, fluid properties like density and compressibility can affect the meaning of conversions.
