About Converting Teaspoon per Years to Metric teaspoons per Millisecond
Teaspoon per Years and Metric teaspoon 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
metric teaspoons per millisecond = teaspoon per years × 3.123826e-11
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 metric teaspoon per millisecond equals 0.005 base units, so dividing one by the other gives the direct teaspoon per years-to-metric teaspoon per millisecond factor of 3.123826e-11.
Simple example
1 tsp/yr × 3.123826e-11 = 3.123826e-11 metric tsp/ms
1 teaspoon per years = 3.123826e-11 metric teaspoons per millisecond.
Real-world example
60 tsp/yr × 3.123826e-11 = 1.874296e-9 metric tsp/ms
60 teaspoon per years = 1.874296e-9 metric teaspoons per millisecond.

Frequently asked questions
How many metric teaspoons per millisecond are in 1 teaspoon per years?
1 teaspoon per years equals 3.123826e-11 metric teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per years to metric teaspoon per millisecond?
Multiply the teaspoon per years value by 3.123826e-11. The converter above does this instantly to whatever precision you set.
How do I convert metric teaspoon per millisecond back to teaspoon per years?
Use the reverse factor: 1 metric teaspoon per millisecond equals 32,012,024,740 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 metric teaspoon per millisecond?
Metric teaspoon per Millisecond (metric tsp/ms) is a unit of flow rate.
Is the teaspoon per years to metric teaspoon per millisecond conversion exact?
Yes. Both teaspoon per years and metric teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 3.123826e-11 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.
