How it works
Enter a value, select Cubic metre per hour and US gallon per minute, then MimiFile calculates the result instantly using the conversion model for this category.
Convert cubic metres per hour (m³/h) to US gallons per minute (US GPM) for pumps, piping, water systems, HVAC and process equipment.
Enter a value, select Cubic metre per hour and US gallon per minute, then MimiFile calculates the result instantly using the conversion model for this category.
Multiply m³/h by approximately 4.4028675393 to get US GPM. This route uses the US liquid gallon, not the imperial gallon.
Volumetric flow uses a base-unit scale model.
US GPM = m³/h × approximately 4.4028675393. One cubic metre is 1000 litres, one US gallon is 3.785411784 litres and one hour is 60 minutes.
The US liquid gallon is smaller than the imperial gallon. Confirm which gallon system is used on pump curves, valve data and equipment specifications before comparing values.
Useful when a specification, map, recipe, technical document or device uses US gallon per minute while your source value is in Cubic metre per hour.
