About Converting Cubic yard per Hours to Cubic Millimeters per Millisecond
Cubic yard per Hours and Cubic Millimeter 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
cubic millimeters per millisecond = cubic yard per hours × 212.37634944
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 cubic millimeter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct cubic yard per hours-to-cubic millimeter per millisecond factor of 212.37634944.
Simple example
1 yd3/h × 212.3763494 = 212.3763494 mm3/ms
1 cubic yard per hours = 212.3763494 cubic millimeters per millisecond.
Real-world example
60 yd3/h × 212.3763494 = 12,742.58097 mm3/ms
60 cubic yard per hours = 12,742.58097 cubic millimeters per millisecond.

How do I convert cubic millimeter per millisecond back to cubic yard per hours?
Use the reverse factor: 1 cubic millimeter per millisecond equals 0.0047086222 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 cubic millimeter per millisecond?
Cubic Millimeter per Millisecond (mm3/ms) is a unit of flow rate.
Is the cubic yard per hours to cubic millimeter per millisecond conversion exact?
Yes. Both cubic yard per hours and cubic millimeter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 212.3763494 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.
