About Converting Cubic foot per Seconds to Teaspoon per Years
Cubic foot per Seconds and Teaspoon 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. 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
teaspoon per years = cubic foot per seconds × 181295918732
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 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct cubic foot per seconds-to-teaspoon per years factor of 181295918732.
Simple example
1 ft3/s × 181295918700 = 181,295,918,700 tsp/yr
1 cubic foot per seconds = 181,295,918,700 teaspoon per years.
Real-world example
60 ft3/s × 181295918700 = 1.087776e+13 tsp/yr
60 cubic foot per seconds = 1.087776e+13 teaspoon per years.

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 teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
Is the cubic foot per seconds to teaspoon per years conversion exact?

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.
