About Converting Gallons per Millisecond to Cubic Millimeter per Days
Gallon per Millisecond 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 = gallons per millisecond × 3.270596e+14
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 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 millisecond-to-cubic millimeter per days factor of 3.270596e+14.
Simple example
1 gal/ms × 3.270596e+14 = 3.270596e+14 mm3/d
1 gallon per millisecond = 3.270596e+14 cubic millimeter per days.
Real-world example
60 gal/ms × 3.270596e+14 = 1.962357e+16 mm3/d
60 gallons per millisecond = 1.962357e+16 cubic millimeter per days.

Frequently asked questions
How many cubic millimeter per days are in 1 gallon per millisecond?
1 gallon per millisecond equals 3.270596e+14 cubic millimeter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic millimeter per days?
Multiply the gallon per millisecond value by 3.270596e+14. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per days back to gallon per millisecond?
Use the reverse factor: 1 cubic millimeter per days equals 3.057547e-15 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) 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 millisecond to cubic millimeter per days conversion exact?
Yes. Both gallon per millisecond and cubic millimeter per days are defined by fixed standards rather than physical artifacts, so the factor of 3.270596e+14 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.
