About Converting Cubic yard per Hours to Imperial quarts per Millisecond
Cubic yard per Hours and Imperial quart 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
imperial quarts per millisecond = cubic yard per hours × 0.000186865063771
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 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct cubic yard per hours-to-imperial quart per millisecond factor of 0.000186865063771.
Simple example
1 yd3/h × 0.0001868650638 = 0.0001868651 imp qt/ms
1 cubic yard per hours = 0.0001868651 imperial quarts per millisecond.
Real-world example
60 yd3/h × 0.0001868650638 = 0.0112119038 imp qt/ms
60 cubic yard per hours = 0.0112119038 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 cubic yard per hours?
1 cubic yard per hours equals 0.0001868651 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic yard per hours to imperial quart per millisecond?
Multiply the cubic yard per hours value by 0.0001868650638. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to cubic yard per hours?
Use the reverse factor: 1 imperial quart per millisecond equals 5,351.455108 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 imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the cubic yard per hours to imperial quart per millisecond conversion exact?
Yes. Both cubic yard per hours and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.0001868650638 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.
