About Converting Gallon per Hours to Cubic Millimeter per Days
Gallon per Hours and Cubic Millimeter per Days 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 days = gallon per hours × 90849882.816
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per hours equals 0.00000105150327333 base units, and 1 cubic millimeter per days equals 1.157407e-14 base units, so dividing one by the other gives the direct gallon per hours-to-cubic millimeter per days factor of 90849882.816.
Simple example
1 gal/h × 90849882.82 = 90,849,882.82 mm3/d
1 gallon per hours = 90,849,882.82 cubic millimeter per days.
Real-world example
60 gal/h × 90849882.82 = 5,450,992,969 mm3/d
60 gallon per hours = 5,450,992,969 cubic millimeter per days.

Frequently asked questions
How many cubic millimeter per days are in 1 gallon per hours?
1 gallon per hours equals 90,849,882.82 cubic millimeter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per hours to cubic millimeter per days?
Multiply the gallon per hours value by 90849882.82. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per days back to gallon per hours?
Use the reverse factor: 1 cubic millimeter per days equals 1.100717e-8 gallon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per hours?
Gallon per Hours (gal/h) is a unit of flow rate.
What is a cubic millimeter per days?
Cubic Millimeter per Days (mm3/d) is a unit of flow rate.
Is the gallon per hours to cubic millimeter per days conversion exact?
Yes. Both gallon per hours and cubic millimeter per days are defined by fixed standards rather than physical artifacts, so the factor of 90849882.82 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.
