About Converting Imperial gallon per Years to Imperial quarts per Millisecond
Imperial gallon per Years 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 = imperial gallon per years × 1.26755e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 imperial gallon per years equals 1.440599e-10 base units, and 1 imperial quart per millisecond equals 1.1365225 base units, so dividing one by the other gives the direct imperial gallon per years-to-imperial quart per millisecond factor of 1.26755e-10.
Simple example
1 imp gal/yr × 1.26755e-10 = 1.26755e-10 imp qt/ms
1 imperial gallon per years = 1.26755e-10 imperial quarts per millisecond.
Real-world example
60 imp gal/yr × 1.26755e-10 = 7.605297e-9 imp qt/ms
60 imperial gallon per years = 7.605297e-9 imperial quarts per millisecond.

Frequently asked questions
How many imperial quarts per millisecond are in 1 imperial gallon per years?
1 imperial gallon per years equals 1.26755e-10 imperial quarts per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert imperial gallon per years to imperial quart per millisecond?
Multiply the imperial gallon per years value by 1.26755e-10. The converter above does this instantly to whatever precision you set.
How do I convert imperial quart per millisecond back to imperial gallon per years?
Use the reverse factor: 1 imperial quart per millisecond equals 7,889,238,000 imperial gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a imperial gallon per years?
Imperial gallon per Years (imp gal/yr) 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 imperial gallon per years to imperial quart per millisecond conversion exact?
Yes. Both imperial gallon per years and imperial quart per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.26755e-10 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.
