About Converting Gallon per Years to Teaspoons per Millisecond
Gallon per Years and 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
teaspoons per millisecond = gallon per years × 2.433695e-8
This factor comes from each unit's defined relationship to the category's base unit: 1 gallon per years equals 1.199549e-10 base units, and 1 teaspoon per millisecond equals 0.00492892159375 base units, so dividing one by the other gives the direct gallon per years-to-teaspoon per millisecond factor of 2.433695e-8.
Simple example
1 gal/yr × 2.433695e-8 = 2.433695e-8 tsp/ms
1 gallon per years = 2.433695e-8 teaspoons per millisecond.
Real-world example
60 gal/yr × 2.433695e-8 = 0.0000014602 tsp/ms
60 gallon per years = 0.0000014602 teaspoons per millisecond.

Frequently asked questions
How many teaspoons per millisecond are in 1 gallon per years?
1 gallon per years equals 2.433695e-8 teaspoons per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert gallon per years to teaspoon per millisecond?
Multiply the gallon per years value by 2.433695e-8. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per millisecond back to gallon per years?
Use the reverse factor: 1 teaspoon per millisecond equals 41,089,781.25 gallon per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a gallon per years?
Gallon per Years (gal/yr) is a unit of flow rate.
What is a teaspoon per millisecond?
Teaspoon per Millisecond (tsp/ms) is a unit of flow rate.
Is the gallon per years to teaspoon per millisecond conversion exact?
Yes. Both gallon per years and teaspoon per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 2.433695e-8 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.
