About Converting Gallons per Millisecond to Cubic foot per Days
Gallon per Millisecond and Cubic foot 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 foot per days = gallons per millisecond × 11550000
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 foot per days equals 3.277413e-7 base units, so dividing one by the other gives the direct gallon per millisecond-to-cubic foot per days factor of 11550000.
Simple example
1 gal/ms × 11550000 = 11,550,000 ft3/d
1 gallon per millisecond = 11,550,000 cubic foot per days.
Real-world example
60 gal/ms × 11550000 = 693,000,000 ft3/d
60 gallons per millisecond = 693,000,000 cubic foot per days.

Frequently asked questions
How many cubic foot per days are in 1 gallon per millisecond?
1 gallon per millisecond equals 11,550,000 cubic foot per days, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to cubic foot per days?
Multiply the gallon per millisecond value by 11550000. The converter above does this instantly to whatever precision you set.
How do I convert cubic foot per days back to gallon per millisecond?
Use the reverse factor: 1 cubic foot per days equals 8.658009e-8 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 foot per days?
Cubic foot per Days (ft3/d) is a unit of flow rate.
Is the gallon per millisecond to cubic foot per days conversion exact?
Yes. Both gallon per millisecond and cubic foot per days are defined by fixed standards rather than physical artifacts, so the factor of 11550000 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.
