About Converting Milliliter per Days to Teaspoon per Years
Milliliter per Days 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. Both are volumetric flow rate units.
Formula
teaspoon per years = milliliter per days × 74.1019091201
This factor comes from each unit's defined relationship to the category's base unit: 1 milliliter per days equals 1.157407e-11 base units, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct milliliter per days-to-teaspoon per years factor of 74.1019091201.
Simple example
1 mL/d × 74.10190912 = 74.10190912 tsp/yr
1 milliliter per days = 74.10190912 teaspoon per years.
Real-world example
60 mL/d × 74.10190912 = 4,446.114547 tsp/yr
60 milliliter per days = 4,446.114547 teaspoon per years.

Frequently asked questions
How many teaspoon per years are in 1 milliliter per days?
1 milliliter per days equals 74.10190912 teaspoon per years, using the exact defined conversion factor rather than an estimate.
How do I convert milliliter per days to teaspoon per years?
Multiply the milliliter per days value by 74.10190912. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per years back to milliliter per days?
Use the reverse factor: 1 teaspoon per years equals 0.013494929 milliliter per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a milliliter per days?
Milliliter per Days (mL/d) is a unit of flow rate.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
Is the milliliter per days to teaspoon per years conversion exact?
Yes. Both milliliter per days and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 74.10190912 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.
