About Converting Teaspoon per Years to Microliters per Millisecond
Teaspoon per Years and Microliter per Millisecond 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
microliters per millisecond = teaspoon per years × 1.561913e-7
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per years equals 1.561913e-13 base units, and 1 microliter per millisecond equals 0.000001 base units, so dividing one by the other gives the direct teaspoon per years-to-microliter per millisecond factor of 1.561913e-7.
Simple example
1 tsp/yr × 1.561913e-7 = 1.561913e-7 uL/ms
1 teaspoon per years = 1.561913e-7 microliters per millisecond.
Real-world example
60 tsp/yr × 1.561913e-7 = 0.0000093715 uL/ms
60 teaspoon per years = 0.0000093715 microliters per millisecond.

Frequently asked questions
How many microliters per millisecond are in 1 teaspoon per years?
1 teaspoon per years equals 1.561913e-7 microliters per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to microliter per millisecond?
Multiply the teaspoon per years value by 1.561913e-7. The converter above does this instantly to whatever precision you set.
How do I convert microliter per millisecond back to teaspoon per years?
Use the reverse factor: 1 microliter per millisecond equals 6,402,404.948 teaspoon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per years?
Teaspoon per Years (tsp/yr) is a unit of flow rate.
What is a microliter per millisecond?
Microliter per Millisecond (uL/ms) is a unit of flow rate.
Is the teaspoon per years to microliter per millisecond conversion exact?
Yes. Both teaspoon per years and microliter per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 1.561913e-7 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.
