About Converting Cubic Meter per Years to Gallons per Millisecond
Cubic Meter per Years and Gallon per Millisecond 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
gallons per millisecond = cubic meter per years × 8.371279e-9
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per years equals 3.168874e-8 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic meter per years-to-gallon per millisecond factor of 8.371279e-9.
Simple example
1 m3/yr × 8.371279e-9 = 8.371279e-9 gal/ms
1 cubic meter per years = 8.371279e-9 gallons per millisecond.
Real-world example
60 m3/yr × 8.371279e-9 = 5.022767e-7 gal/ms
60 cubic meter per years = 5.022767e-7 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic meter per years?
1 cubic meter per years equals 8.371279e-9 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per years to gallon per millisecond?
Multiply the cubic meter per years value by 8.371279e-9. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic meter per years?
Use the reverse factor: 1 gallon per millisecond equals 119,456,058 cubic meter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per years?
Cubic Meter per Years (m3/yr) is a unit of flow rate.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
Is the cubic meter per years to gallon per millisecond conversion exact?
Yes. Both cubic meter per years and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 8.371279e-9 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.
