About Converting Teaspoon per Days to Metric teaspoon per Years
Teaspoon per Days and Metric 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. Both are volumetric flow rate units.
Formula
metric teaspoon per years = teaspoon per days × 360.050329041
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per days equals 5.70477e-11 base units, and 1 metric teaspoon per years equals 1.584437e-13 base units, so dividing one by the other gives the direct teaspoon per days-to-metric teaspoon per years factor of 360.050329041.
Simple example
1 tsp/d × 360.050329 = 360.050329 metric tsp/yr
1 teaspoon per days = 360.050329 metric teaspoon per years.
Real-world example
60 tsp/d × 360.050329 = 21,603.01974 metric tsp/yr
60 teaspoon per days = 21,603.01974 metric teaspoon per years.

What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
What is a metric teaspoon per years?
Metric teaspoon per Years (metric tsp/yr) is a unit of flow rate.
Is the teaspoon per days to metric teaspoon per years conversion exact?
Yes. Both teaspoon per days and metric teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 360.050329 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.
