About Converting Teaspoon per Hours to Fluid ounces per Millisecond
Teaspoon per Hours and Fluid ounce 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
fluid ounces per millisecond = teaspoon per hours × 4.62963e-8
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 fluid ounce per millisecond equals 0.0295735295625 base units, so dividing one by the other gives the direct teaspoon per hours-to-fluid ounce per millisecond factor of 4.62963e-8.
Simple example
1 tsp/h × 4.62963e-8 = 4.62963e-8 fl oz/ms
1 teaspoon per hours = 4.62963e-8 fluid ounces per millisecond.
Real-world example
60 tsp/h × 4.62963e-8 = 0.0000027778 fl oz/ms
60 teaspoon per hours = 0.0000027778 fluid ounces per millisecond.

Frequently asked questions
How many fluid ounces per millisecond are in 1 teaspoon per hours?
1 teaspoon per hours equals 4.62963e-8 fluid ounces per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to fluid ounce per millisecond?
Multiply the teaspoon per hours value by 4.62963e-8. The converter above does this instantly to whatever precision you set.
How do I convert fluid ounce per millisecond back to teaspoon per hours?
Use the reverse factor: 1 fluid ounce per millisecond equals 21,600,000 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 fluid ounce per millisecond?
Fluid ounce per Millisecond (fl oz/ms) is a unit of flow rate.
Is the teaspoon per hours to fluid ounce per millisecond conversion exact?
Yes. Both teaspoon per hours and fluid ounce per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 4.62963e-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.
