About Converting Teaspoon per Seconds to Microliter per Days
Teaspoon per Seconds and Microliter per Days 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 days = teaspoon per seconds × 425858825.7
This factor comes from each unit's defined relationship to the category's base unit: 1 teaspoon per seconds equals 0.00000492892159375 base units, and 1 microliter per days equals 1.157407e-14 base units, so dividing one by the other gives the direct teaspoon per seconds-to-microliter per days factor of 425858825.7.
Simple example
1 tsp/s × 425858825.7 = 425,858,825.7 uL/d
1 teaspoon per seconds = 425,858,825.7 microliter per days.
Real-world example
60 tsp/s × 425858825.7 = 25,551,529,540 uL/d
60 teaspoon per seconds = 25,551,529,540 microliter per days.

Frequently asked questions
How many microliter per days are in 1 teaspoon per seconds?
1 teaspoon per seconds equals 425,858,825.7 microliter per days, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per seconds to microliter per days?
Multiply the teaspoon per seconds value by 425858825.7. The converter above does this instantly to whatever precision you set.
How do I convert microliter per days back to teaspoon per seconds?
Use the reverse factor: 1 microliter per days equals 2.348196e-9 teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a teaspoon per seconds?
Teaspoon per Seconds (tsp/s) is a unit of flow rate.
What is a microliter per days?
Microliter per Days (uL/d) is a unit of flow rate.
Is the teaspoon per seconds to microliter per days conversion exact?
Yes. Both teaspoon per seconds and microliter per days are defined by fixed standards rather than physical artifacts, so the factor of 425858825.7 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.
