About Converting Gallon per Months to Cubic Millimeter per Seconds
Gallon per Months and Cubic Millimeter per Seconds 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 seconds = gallon per months × 1.43945908997
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per months equals 1.439459e-9 base units, and 1 cubic millimeter per seconds equals 1e-9 base units, so dividing one by the other gives the direct gallon per months-to-cubic millimeter per seconds factor of 1.43945908997.
Simple example
1 gal/mo × 1.43945909 = 1.43945909 mm3/s
1 gallon per months = 1.43945909 cubic millimeter per seconds.
Real-world example
60 gal/mo × 1.43945909 = 86.3675454 mm3/s
60 gallon per months = 86.3675454 cubic millimeter per seconds.

Frequently asked questions
How many cubic millimeter per seconds are in 1 gallon per months?
1 gallon per months equals 1.43945909 cubic millimeter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per months to cubic millimeter per seconds?
Multiply the gallon per months value by 1.43945909. The converter above does this instantly to whatever precision you set.
How do I convert cubic millimeter per seconds back to gallon per months?
Use the reverse factor: 1 cubic millimeter per seconds equals 0.694705398 gallon per months. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per months?
Gallon per Months (gal/mo) is a unit of flow rate.
What is a cubic millimeter per seconds?
Cubic Millimeter per Seconds (mm3/s) is a unit of flow rate.
Is the gallon per months to cubic millimeter per seconds conversion exact?
Yes. Both gallon per months and cubic millimeter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.43945909 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.
