How it works
Enter a value, select US gallon per minute and Cubic metre per hour, then MimiFile calculates the result instantly using the conversion model for this category.
Convert US gallons per minute (US GPM) to cubic metres per hour (m³/h) for pumps, water systems and engineering flow specifications.
Enter a value, select US gallon per minute and Cubic metre per hour, then MimiFile calculates the result instantly using the conversion model for this category.
Multiply US GPM by approximately 0.22712470704 to get m³/h. The conversion combines US gallons to cubic metres with minutes to hours.
Volumetric flow uses a base-unit scale model.
m³/h = US GPM × 0.22712470704. One US gallon is 0.003785411784 m³ and one hour contains 60 minutes.
US GPM is common on pumps and equipment in US customary units, while m³/h is widely used in metric engineering, water and HVAC specifications.
Useful when a specification, map, recipe, technical document or device uses Cubic metre per hour while your source value is in US gallon per minute.
