About Converting Liters per Millisecond to Teaspoon per Years
Liter per Millisecond 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 = liters per millisecond × 6.402405e+12
This factor comes from each unit's defined relationship to the category's base unit: 1 liter per millisecond equals 1 base unit, and 1 teaspoon per years equals 1.561913e-13 base units, so dividing one by the other gives the direct liter per millisecond-to-teaspoon per years factor of 6.402405e+12.
Simple example
1 L/ms × 6.402405e+12 = 6.402405e+12 tsp/yr
1 liter per millisecond = 6.402405e+12 teaspoon per years.
Real-world example
60 L/ms × 6.402405e+12 = 3.841443e+14 tsp/yr
60 liters per millisecond = 3.841443e+14 teaspoon per years.

Frequently asked questions
How many teaspoon per years are in 1 liter per millisecond?
1 liter per millisecond equals 6.402405e+12 teaspoon per years, using the exact defined conversion factor rather than an estimate.
How do I convert liter per millisecond to teaspoon per years?
Multiply the liter per millisecond value by 6.402405e+12. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per years back to liter per millisecond?
Use the reverse factor: 1 teaspoon per years equals 1.561913e-13 liters per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a liter per millisecond?
Liter per Millisecond (L/ms) 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 liter per millisecond to teaspoon per years conversion exact?
Yes. Both liter per millisecond and teaspoon per years are defined by fixed standards rather than physical artifacts, so the factor of 6.402405e+12 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.
