About Converting Cubic yard per Hours to Gallons per Millisecond
Cubic yard per Hours 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 yard per hours × 0.0000561038961039
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic yard per hours equals 0.00021237634944 base units, and 1 gallon per millisecond equals 3.785411784 base units, so dividing one by the other gives the direct cubic yard per hours-to-gallon per millisecond factor of 0.0000561038961039.
Simple example
1 yd3/h × 0.0000561038961 = 0.0000561039 gal/ms
1 cubic yard per hours = 0.0000561039 gallons per millisecond.
Real-world example
60 yd3/h × 0.0000561038961 = 0.0033662338 gal/ms
60 cubic yard per hours = 0.0033662338 gallons per millisecond.

Frequently asked questions
How many gallons per millisecond are in 1 cubic yard per hours?
1 cubic yard per hours equals 0.0000561039 gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per hours to gallon per millisecond?
Multiply the cubic yard per hours value by 0.0000561038961. The converter above does this instantly to whatever precision you set.
How do I convert gallon per millisecond back to cubic yard per hours?
Use the reverse factor: 1 gallon per millisecond equals 17,824.07407 cubic yard per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic yard per hours?
Cubic yard per Hours (yd3/h) 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 yard per hours to gallon per millisecond conversion exact?
Yes. Both cubic yard per hours and gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0000561038961 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.
