About Converting Gallons per Millisecond to Cubic Meter per Days
Gallon per Millisecond and Cubic Meter 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 meter per days = gallons per millisecond × 327059.578138
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 meter per days equals 0.0000115740740741 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic meter per days factor of 327059.578138.
Simple example
1 gal/ms × 327059.5781 = 327,059.5781 m3/d
1 gallon per millisecond = 327,059.5781 cubic meter per days.
Real-world example
60 gal/ms × 327059.5781 = 19,623,574.69 m3/d
60 gallons per millisecond = 19,623,574.69 cubic meter per days.

Frequently asked questions
How many cubic meter per days are in 1 gallon per millisecond?
1 gallon per millisecond equals 327,059.5781 cubic meter per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic meter per days?
Multiply the gallon per millisecond value by 327059.5781. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per days back to gallon per millisecond?
Use the reverse factor: 1 cubic meter per days equals 0.0000030575 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 meter per days?
Cubic Meter per Days (m3/d) is a unit of flow rate.
Is the gallon per millisecond to cubic meter per days conversion exact?
Yes. Both gallon per millisecond and cubic meter per days are defined by fixed standards rather than physical artifacts, so the factor of 327059.5781 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.
