About Converting Cubic Meter per Seconds to Imperial quarts per Millisecond
Cubic Meter per Seconds 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. Cubic Meter per Seconds is most often used for used by hydrologists and water-resource engineers internationally to report river and reservoir discharge at large scales.
Formula
imperial quarts per millisecond = cubic meter per seconds × 0.879876993196
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic meter per seconds equals 1 base unit, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct cubic meter per seconds-to-imperial quart per millisecond factor of 0.879876993196.
Simple example
1 m3/s × 0.8798769932 = 0.8798769932 imp qt/ms
1 cubic meter per seconds = 0.8798769932 imperial quarts per millisecond.
Real-world example
60 m3/s × 0.8798769932 = 52.79261959 imp qt/ms
60 cubic meter per seconds = 52.79261959 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 cubic meter per seconds?
1 cubic meter per seconds equals 0.8798769932 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert cubic meter per seconds to imperial quart per millisecond?
Multiply the cubic meter per seconds value by 0.8798769932. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to cubic meter per seconds?
Use the reverse factor: 1 imperial quart per millisecond equals 1.1365225 cubic meter per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic meter per seconds?
Cubic Meter per Seconds (m3/s) measures volumetric flow rate. The SI coherent unit for volumetric flow rate — one cubic meter of volume passing a point every second. It is classified as a SI coherent derived unit.
What is a imperial quart per millisecond?
Imperial quart per Millisecond (imp qt/ms) is a unit of flow rate.
Is the cubic meter per seconds to imperial quart per millisecond conversion exact?
Yes. Both cubic meter per seconds and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.8798769932 used above is exact to as many digits as you choose to display.
Where is the cubic meter per seconds still used today?
Used internationally in hydrology and large-scale water-resource engineering
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.
