About Converting Gallons per Fortnight to Imperial gallons per Millisecond
Gallon per Fortnight 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 = gallons per fortnight × 6.88388e-10
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per fortnight equals 3.129474e-9 base units, and 1 imperial gallon per millisecond equals 4.54609 base units, so dividing one by the other gives the direct gallon per fortnight-to-imperial gallon per millisecond factor of 6.88388e-10.
Simple example
1 gal/fn × 6.88388e-10 = 6.88388e-10 imp gal/ms
1 gallon per fortnight = 6.88388e-10 imperial gallons per millisecond.
Real-world example
60 gal/fn × 6.88388e-10 = 4.130328e-8 imp gal/ms
60 gallons per fortnight = 4.130328e-8 imperial gallons per millisecond.

Frequently asked questions
How many imperial gallons per millisecond are in 1 gallon per fortnight?
1 gallon per fortnight equals 6.88388e-10 imperial gallons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per fortnight to imperial gallon per millisecond?
Multiply the gallon per fortnight value by 6.88388e-10. The converter above does this instantly to whatever precision you set.
How do I convert imperial gallon per millisecond back to gallon per fortnight?
Use the reverse factor: 1 imperial gallon per millisecond equals 1,452,669,030 gallons per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) 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 gallon per fortnight to imperial gallon per millisecond conversion exact?
Yes. Both gallon per fortnight and imperial gallon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 6.88388e-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.
