About Converting Teaspoons per Fortnight to Milliliter per Years
Teaspoon per Fortnight and Milliliter per Years 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
milliliter per years = teaspoons per fortnight × 128.589403229
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per fortnight equals 4.074836e-12 base units, and 1 milliliter per years equals 3.168874e-14 base units, so dividing one by the other gives the direct teaspoon per fortnight-to-milliliter per years factor of 128.589403229.
Simple example
1 tsp/fn × 128.5894032 = 128.5894032 mL/yr
1 teaspoon per fortnight = 128.5894032 milliliter per years.
Real-world example
60 tsp/fn × 128.5894032 = 7,715.364194 mL/yr
60 teaspoons per fortnight = 7,715.364194 milliliter per years.

Frequently asked questions
How many milliliter per years are in 1 teaspoon per fortnight?
1 teaspoon per fortnight equals 128.5894032 milliliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per fortnight to milliliter per years?
Multiply the teaspoon per fortnight value by 128.5894032. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per years back to teaspoon per fortnight?
Use the reverse factor: 1 milliliter per years equals 0.0077766906 teaspoons per fortnight. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per fortnight?
Teaspoon per Fortnight (tsp/fn) is a unit of flow rate.
What is a milliliter per years?
Milliliter per Years (mL/yr) is a unit of flow rate.
Is the teaspoon per fortnight to milliliter per years conversion exact?
Yes. Both teaspoon per fortnight and milliliter per years are defined by fixed standards rather than physical artifacts, so the factor of 128.5894032 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.
