About Converting Imperial gallons per Millisecond to Cubic Meters per Millisecond

Imperial gallon per Millisecond and Cubic Meter 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 meters per millisecond = imperial gallons per millisecond × 0.00454609

This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per millisecond equals 4.54609 base units, and 1 cubic meter per millisecond equals 1000 base units, so dividing one by the other gives the direct imperial gallon per millisecond-to-cubic meter per millisecond factor of 0.00454609.

Simple example

1 imp gal/ms × 0.00454609 = 0.00454609 m3/ms

1 imperial gallon per millisecond = 0.00454609 cubic meters per millisecond.

Real-world example

60 imp gal/ms × 0.00454609 = 0.2727654 m3/ms

60 imperial gallons per millisecond = 0.2727654 cubic meters per millisecond.

Frequently asked questions

How many cubic meters per millisecond are in 1 imperial gallon per millisecond?

1 imperial gallon per millisecond equals 0.00454609 cubic meters per millisecond, using the exact defined conversion factor rather than an estimate.

How do I convert imperial gallon per millisecond to cubic meter per millisecond?

Multiply the imperial gallon per millisecond value by 0.00454609. The converter above does this instantly to whatever precision you set.

How do I convert cubic meter per millisecond back to imperial gallon per millisecond?

Use the reverse factor: 1 cubic meter per millisecond equals 219.9692483 imperial gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.

What is a imperial gallon per millisecond?

Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.

What is a cubic meter per millisecond?

Cubic Meter per Millisecond (m3/ms) is a unit of flow rate.

Is the imperial gallon per millisecond to cubic meter per millisecond conversion exact?

Yes. Both imperial gallon per millisecond and cubic meter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.00454609 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.
