About Converting Quarts per Millisecond to Cubic Meter per Hours
Quart per Millisecond and Cubic Meter per Hours 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 meter per hours = quarts per millisecond × 3406.8706056
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 cubic meter per hours equals 0.000277777777778 base units, so dividing one by the other gives the direct quart per millisecond-to-cubic meter per hours factor of 3406.8706056.
Simple example
1 qt/ms × 3406.870606 = 3,406.870606 m3/h
1 quart per millisecond = 3,406.870606 cubic meter per hours.
Real-world example
60 qt/ms × 3406.870606 = 204,412.2363 m3/h
60 quarts per millisecond = 204,412.2363 cubic meter per hours.

Understanding the Quart per Millisecond (qt/ms)
Volumetric flow rate.
Understanding the Cubic Meter per Hours
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Where it's used: Standard flow-rate unit for HVAC and industrial equipment ratings internationally, outside the US
Uses of the Cubic Meter per Hours today
- HVAC equipment airflow and liquid-flow ratings
- Industrial pump and system flow specifications
- Building ventilation system design
Cubic Meter per Hours — sources
- ISO 5167 (flow measurement standards) — Cubic meters per hour as a standard industrial flow-rate unit.

Frequently asked questions
How many cubic meter per hours are in 1 quart per millisecond?
1 quart per millisecond equals 3,406.870606 cubic meter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to cubic meter per hours?
Multiply the quart per millisecond value by 3406.870606. The converter above does this instantly to whatever precision you set.
How do I convert cubic meter per hours back to quart per millisecond?
Use the reverse factor: 1 cubic meter per hours equals 0.0002935245 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
What is a cubic meter per hours?
Cubic Meter per Hours (m3/h) measures volumetric flow rate. One cubic meter of volume passing a point every hour — a common scale for equipment and system flow ratings. It is classified as a metric derived flow-rate unit.
Is the quart per millisecond to cubic meter per hours conversion exact?
Yes. Both quart per millisecond and cubic meter per hours are defined by fixed standards rather than physical artifacts, so the factor of 3406.870606 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.
