About Converting Cubic yards per Millisecond to Gallon per Days
Cubic yard per Millisecond and Gallon 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
gallon per days = cubic yards per millisecond × 17450555844.2
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per millisecond equals 764.554857984 base units, and 1 gallon per days equals 4.381264e-8 base units, so dividing one by the other gives the direct cubic yard per millisecond-to-gallon per days factor of 17450555844.2.
Simple example
1 yd3/ms × 17450555840 = 17,450,555,840 gal/d
1 cubic yard per millisecond = 17,450,555,840 gallon per days.
Real-world example
60 yd3/ms × 17450555840 = 1.047033e+12 gal/d
60 cubic yards per millisecond = 1.047033e+12 gallon per days.

Frequently asked questions
How many gallon per days are in 1 cubic yard per millisecond?
1 cubic yard per millisecond equals 17,450,555,840 gallon per days, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per millisecond to gallon per days?
Multiply the cubic yard per millisecond value by 17450555840. The converter above does this instantly to whatever precision you set.
How do I convert gallon per days back to cubic yard per millisecond?
Use the reverse factor: 1 gallon per days equals 5.730476e-11 cubic yards per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per millisecond?
Cubic yard per Millisecond (yd3/ms) is a unit of flow rate.
What is a gallon per days?
Gallon per Days (gal/d) is a unit of flow rate.
Is the cubic yard per millisecond to gallon per days conversion exact?
Yes. Both cubic yard per millisecond and gallon per days are defined by fixed standards rather than physical artifacts, so the factor of 17450555840 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.
