About Converting Gallons per Millisecond to Gallons per Fortnight
Gallon per Millisecond and Gallon per Fortnight 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
gallons per fortnight = gallons per millisecond × 1209600000
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per millisecond equals 3.785411784 base units, and 1 gallon per fortnight equals 3.129474e-9 base units, so dividing one by the other gives the direct gallon per millisecond-to-gallon per fortnight factor of 1209600000.
Simple example
1 gal/ms × 1209600000 = 1,209,600,000 gal/fn
1 gallon per millisecond = 1,209,600,000 gallons per fortnight.
Real-world example
60 gal/ms × 1209600000 = 72,576,000,000 gal/fn
60 gallons per millisecond = 72,576,000,000 gallons per fortnight.

Reverse conversion: Gallon per Fortnight to Gallon per Millisecond
1 gal/fn × 8.267196e-10 = 8.267196e-10 gal/ms
1 gallon per fortnight = 8.267196e-10 gallons per millisecond.
gallons per millisecond = gallons per fortnight × 8.267196e-10

Frequently asked questions
How many gallons per fortnight are in 1 gallon per millisecond?
1 gallon per millisecond equals 1,209,600,000 gallons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per millisecond to gallon per fortnight?
Multiply the gallon per millisecond value by 1209600000. The converter above does this instantly to whatever precision you set.
How do I convert gallon per fortnight back to gallon per millisecond?
Use the reverse factor: 1 gallon per fortnight equals 8.267196e-10 gallons per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per millisecond?
Gallon per Millisecond (gal/ms) is a unit of flow rate.
What is a gallon per fortnight?
Gallon per Fortnight (gal/fn) is a unit of flow rate.
Is the gallon per millisecond to gallon per fortnight conversion exact?
Yes. Both gallon per millisecond and gallon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 1209600000 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.
