About Converting Imperial gallon per Seconds to Imperial gallons per Millisecond
Imperial gallon per Seconds and Imperial gallon 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 gallons per millisecond = imperial gallon per seconds × 0.001
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per seconds equals 0.00454609 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct imperial gallon per seconds-to-imperial gallon per millisecond factor of 0.001.
Simple example
1 imp gal/s × 0.001 = 0.001 imp gal/ms
1 imperial gallon per seconds = 0.001 imperial gallons per millisecond.
Real-world example
60 imp gal/s × 0.001 = 0.06 imp gal/ms
60 imperial gallon per seconds = 0.06 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 imperial gallon per seconds?
1 imperial gallon per seconds equals 0.001 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per seconds to imperial gallon per millisecond?
Multiply the imperial gallon per seconds value by 0.001. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to imperial gallon per seconds?
Use the reverse factor: 1 imperial gallon per millisecond equals 1,000 imperial gallon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per seconds?
Imperial gallon per Seconds (imp gal/s) is a unit of flow rate.
What is a imperial gallon per millisecond?
Imperial gallon per Millisecond (imp gal/ms) is a unit of flow rate.
Is the imperial gallon per seconds to imperial gallon per millisecond conversion exact?
Yes. Both imperial gallon per seconds and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 0.001 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.
