About Converting Gallons per Millisecond to Cubic Kilometer per Days
Gallon per Millisecond and Cubic Kilometer 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 kilometer per days = gallons per millisecond × 0.000327059578138
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 kilometer per days equals 11574.0740741 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic kilometer per days factor of 0.000327059578138.
Simple example
1 gal/ms × 0.0003270595781 = 0.0003270596 km3/d
1 gallon per millisecond = 0.0003270596 cubic kilometer per days.
Real-world example
60 gal/ms × 0.0003270595781 = 0.0196235747 km3/d
60 gallons per millisecond = 0.0196235747 cubic kilometer per days.

Frequently asked questions
How many cubic kilometer per days are in 1 gallon per millisecond?
1 gallon per millisecond equals 0.0003270596 cubic kilometer per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic kilometer per days?
Multiply the gallon per millisecond value by 0.0003270595781. The converter above does this instantly to whatever precision you set.
How do I convert cubic kilometer per days back to gallon per millisecond?
Use the reverse factor: 1 cubic kilometer per days equals 3,057.546902 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 kilometer per days?
Cubic Kilometer per Days (km3/d) is a unit of flow rate.
Is the gallon per millisecond to cubic kilometer per days conversion exact?
Yes. Both gallon per millisecond and cubic kilometer per days are defined by fixed standards rather than physical artifacts, so the factor of 0.0003270595781 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.
