About Converting Gallon per Seconds to Cubic Millimeter per Hours
Gallon per Seconds and Cubic Millimeter per Hours both measure volumetric flow rate — how much volume passes a point over time — used to size pipes and pumps, monitor river or stream discharge, control industrial processes, and set medical infusion rates. Both are volumetric flow rate units.
Formula
cubic millimeter per hours = gallon per seconds × 13627482422.4
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per seconds equals 0.003785411784 base units, and 1 cubic millimeter per hours equals 2.777778e-13 base units, so dividing one by the other gives the direct gallon per seconds-to-cubic millimeter per hours factor of 13627482422.4.
Simple example
1 gal/s × 13627482420 = 13,627,482,420 mm3/h
1 gallon per seconds = 13,627,482,420 cubic millimeter per hours.
Real-world example
60 gal/s × 13627482420 = 817,648,945,300 mm3/h
60 gallon per seconds = 817,648,945,300 cubic millimeter per hours.

Frequently asked questions
How many cubic millimeter per hours are in 1 gallon per seconds?
1 gallon per seconds equals 13,627,482,420 cubic millimeter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per seconds to cubic millimeter per hours?
Multiply the gallon per seconds value by 13627482420. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per hours back to gallon per seconds?
Use the reverse factor: 1 cubic millimeter per hours equals 7.338113e-11 gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per seconds?
Gallon per Seconds (gal/s) is a unit of flow rate.
What is a cubic millimeter per hours?
Cubic Millimeter per Hours (mm3/h) is a unit of flow rate.
Is the gallon per seconds to cubic millimeter per hours conversion exact?
Yes. Both gallon per seconds and cubic millimeter per hours are defined by fixed standards rather than physical artifacts, so the factor of 13627482420 used above is exact to as many digits as you choose to display.
What's the difference between volumetric and mass flow rate?
Volumetric flow rate measures the volume of fluid passing a point per unit time (for example, liters per second). Mass flow rate measures the mass instead. For a fluid of constant density the two are directly proportional, but for compressible fluids like gases, mass flow is often the more meaningful quantity.
