About Converting Teaspoon per Days to Liter per Years
Teaspoon per Days and Liter 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
liter per years = teaspoon per days × 1.80025164521
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 liter per years equals 3.168874e-11 base units, so dividing one by the other gives the direct teaspoon per days-to-liter per years factor of 1.80025164521.
Simple example
1 tsp/d × 1.800251645 = 1.800251645 L/yr
1 teaspoon per days = 1.800251645 liter per years.
Real-world example
60 tsp/d × 1.800251645 = 108.0150987 L/yr
60 teaspoon per days = 108.0150987 liter per years.

Frequently asked questions
How many liter per years are in 1 teaspoon per days?
1 teaspoon per days equals 1.800251645 liter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per days to liter per years?
Multiply the teaspoon per days value by 1.800251645. The converter above does this instantly to whatever precision you set.
How do I convert liter per years back to teaspoon per days?
Use the reverse factor: 1 liter per years equals 0.5554778981 teaspoon per days. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per days?
Teaspoon per Days (tsp/d) is a unit of flow rate.
What is a liter per years?
Liter per Years (L/yr) is a unit of flow rate.
Is the teaspoon per days to liter per years conversion exact?
Yes. Both teaspoon per days and liter per years are defined by fixed standards rather than physical artifacts, so the factor of 1.800251645 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.
