About Converting Teaspoon per Hours to Quart per Years
Teaspoon per Hours and Quart 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
quart per years = teaspoon per hours × 45.6553125
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per hours equals 1.369145e-9 base units, and 1 quart per years equals 2.998873e-11 base units, so dividing one by the other gives the direct teaspoon per hours-to-quart per years factor of 45.6553125.
Simple example
1 tsp/h × 45.6553125 = 45.6553125 qt/yr
1 teaspoon per hours = 45.6553125 quart per years.
Real-world example
60 tsp/h × 45.6553125 = 2,739.31875 qt/yr
60 teaspoon per hours = 2,739.31875 quart per years.

What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
What is a quart per years?
Quart per Years (qt/yr) is a unit of flow rate.
Is the teaspoon per hours to quart per years conversion exact?
Yes. Both teaspoon per hours and quart per years are defined by fixed standards rather than physical artifacts, so the factor of 45.6553125 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.
