About Converting Cubic Meter per Days to Gallons per Millisecond
Cubic Meter per Days 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 days × 0.00000305754690229
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per days equals 0.0000115740740741 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic meter per days-to-gallon per millisecond factor of 0.00000305754690229.
Simple example
1 m3/d × 0.000003057546902 = 0.0000030575 gal/ms
1 cubic meter per days = 0.0000030575 gallons per millisecond.
Real-world example
60 m3/d × 0.000003057546902 = 0.0001834528 gal/ms
60 cubic meter per days = 0.0001834528 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic meter per days?
1 cubic meter per days equals 0.0000030575 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per days to gallon per millisecond?
Multiply the cubic meter per days value by 0.000003057546902. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic meter per days?
Use the reverse factor: 1 gallon per millisecond equals 327,059.5781 cubic meter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per days?
Cubic Meter per Days (m3/d) 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 days to gallon per millisecond conversion exact?
Yes. Both cubic meter per days and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.000003057546902 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.
