About Converting Teaspoon per Seconds to Milliliter per Years
Teaspoon per Seconds and Milliliter 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
milliliter per years = teaspoon per seconds × 155541742.146
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 milliliter per years equals 3.168874e-14 base units, so dividing one by the other gives the direct teaspoon per seconds-to-milliliter per years factor of 155541742.146.
Simple example
1 tsp/s × 155541742.1 = 155,541,742.1 mL/yr
1 teaspoon per seconds = 155,541,742.1 milliliter per years.
Real-world example
60 tsp/s × 155541742.1 = 9,332,504,529 mL/yr
60 teaspoon per seconds = 9,332,504,529 milliliter per years.

Frequently asked questions
How many milliliter per years are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 155,541,742.1 milliliter per years, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to milliliter per years?
Multiply the teaspoon per seconds value by 155541742.1. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per years back to teaspoon per seconds?
Use the reverse factor: 1 milliliter per years equals 6.429142e-9 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
What is a milliliter per years?
Milliliter per Years (mL/yr) is a unit of flow rate.
Is the teaspoon per seconds to milliliter per years conversion exact?
Yes. Both teaspoon per seconds and milliliter per years are defined by fixed standards rather than physical artifacts, so the factor of 155541742.1 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.
