About Converting Cubic foot per Seconds to Tablespoons per Fortnight
Cubic foot per Seconds and Tablespoon 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. Cubic foot per Seconds is most often used for the standard unit used by the us geological survey for reporting river and stream discharge at gauging stations.
Formula
tablespoons per fortnight = cubic foot per seconds × 2316399709.09
This factor comes from each unit's defined relationship to the category's base unit: 1 cubic foot per seconds equals 0.028316846592 base units, and 1 tablespoon per fortnight equals 1.222451e-11 base units, so dividing one by the other gives the direct cubic foot per seconds-to-tablespoon per fortnight factor of 2316399709.09.
Simple example
1 ft3/s × 2316399709 = 2,316,399,709 tbsp/fn
1 cubic foot per seconds = 2,316,399,709 tablespoons per fortnight.
Real-world example
60 ft3/s × 2316399709 = 138,983,982,500 tbsp/fn
60 cubic foot per seconds = 138,983,982,500 tablespoons per fortnight.

Frequently asked questions
How many tablespoons per fortnight are in 1 cubic foot per seconds?
1 cubic foot per seconds equals 2,316,399,709 tablespoons per fortnight, using the exact defined conversion factor rather than an estimate.
How do I convert cubic foot per seconds to tablespoon per fortnight?
Multiply the cubic foot per seconds value by 2316399709. The converter above does this instantly to whatever precision you set.
How do I convert tablespoon per fortnight back to cubic foot per seconds?
Use the reverse factor: 1 tablespoon per fortnight equals 4.317044e-10 cubic foot per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a cubic foot per seconds?
Cubic foot per Seconds (ft3/s) measures volumetric flow rate. One cubic foot of volume passing a point every second. It is classified as a US customary flow-rate unit.
What is a tablespoon per fortnight?
Tablespoon per Fortnight (tbsp/fn) is a unit of flow rate.
Is the cubic foot per seconds to tablespoon per fortnight conversion exact?
Yes. Both cubic foot per seconds and tablespoon per fortnight are defined by fixed standards rather than physical artifacts, so the factor of 2316399709 used above is exact to as many digits as you choose to display.
Where is the cubic foot per seconds still used today?
United States
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.
