About Converting Teaspoon per Hours to Microliter per Seconds
Teaspoon per Hours and Microliter 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
microliter per seconds = teaspoon per hours × 1.36914488715
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per hours equals 1.369145e-9 base units, and 1 microliter per seconds equals 1e-9 base units, so dividing one by the other gives the direct teaspoon per hours-to-microliter per seconds factor of 1.36914488715.
Simple example
1 tsp/h × 1.369144887 = 1.369144887 uL/s
1 teaspoon per hours = 1.369144887 microliter per seconds.
Real-world example
60 tsp/h × 1.369144887 = 82.14869323 uL/s
60 teaspoon per hours = 82.14869323 microliter per seconds.

Frequently asked questions
How many microliter per seconds are in 1 teaspoon per hours?
1 teaspoon per hours equals 1.369144887 microliter per seconds, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to microliter per seconds?
Multiply the teaspoon per hours value by 1.369144887. The converter above does this instantly to whatever precision you set.
How do I convert microliter per seconds back to teaspoon per hours?
Use the reverse factor: 1 microliter per seconds equals 0.7303828904 teaspoon per hours. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
What is a microliter per seconds?
Microliter per Seconds (uL/s) is a unit of flow rate.
Is the teaspoon per hours to microliter per seconds conversion exact?
Yes. Both teaspoon per hours and microliter per seconds are defined by fixed standards rather than physical artifacts, so the factor of 1.369144887 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.
