About Converting Microliter per Years to Teaspoon per Seconds
Microliter per Years and Teaspoon per Seconds 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 seconds = microliter per years × 6.429142e-12
This factor comes from each unit's defined relationship to the category's base unit: 1 microliter per years equals 3.168874e-17 base units, and 1 teaspoon per seconds equals 0.00000492892159375 base units, so dividing one by the other gives the direct microliter per years-to-teaspoon per seconds factor of 6.429142e-12.
Simple example
1 uL/yr × 6.429142e-12 = 6.429142e-12 tsp/s
1 microliter per years = 6.429142e-12 teaspoon per seconds.
Real-world example
60 uL/yr × 6.429142e-12 = 3.857485e-10 tsp/s
60 microliter per years = 3.857485e-10 teaspoon per seconds.

Frequently asked questions
How many teaspoon per seconds are in 1 microliter per years?
1 microliter per years equals 6.429142e-12 teaspoon per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert microliter per years to teaspoon per seconds?
Multiply the microliter per years value by 6.429142e-12. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per seconds back to microliter per years?
Use the reverse factor: 1 teaspoon per seconds equals 155,541,742,100 microliter per years. You can also use the swap control in the converter above to flip the direction instantly.
What is a microliter per years?
Microliter per Years (uL/yr) is a unit of flow rate.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
Is the microliter per years to teaspoon per seconds conversion exact?
Yes. Both microliter per years and teaspoon per seconds are defined by fixed standards rather than physical artifacts, so the factor of 6.429142e-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.
