About Converting Teaspoon per Hours to Metric cups per Millisecond
Teaspoon per Hours and Metric cup 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
metric cups per millisecond = teaspoon per hours × 5.47658e-9
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 metric cup per millisecond equals 0.25 base units, so dividing one by the other gives the direct teaspoon per hours-to-metric cup per millisecond factor of 5.47658e-9.
Simple example
1 tsp/h × 5.47658e-9 = 5.47658e-9 metric cup/ms
1 teaspoon per hours = 5.47658e-9 metric cups per millisecond.
Real-world example
60 tsp/h × 5.47658e-9 = 3.285948e-7 metric cup/ms
60 teaspoon per hours = 3.285948e-7 metric cups per millisecond.

Frequently asked questions
How many metric cups per millisecond are in 1 teaspoon per hours?
1 teaspoon per hours equals 5.47658e-9 metric cups per millisecond, using the exact defined conversion factor rather than an estimate.
How do I convert teaspoon per hours to metric cup per millisecond?
Multiply the teaspoon per hours value by 5.47658e-9. The converter above does this instantly to whatever precision you set.
How do I convert metric cup per millisecond back to teaspoon per hours?
Use the reverse factor: 1 metric cup per millisecond equals 182,595,722.6 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 metric cup per millisecond?
Metric cup per Millisecond (metric cup/ms) is a unit of flow rate.
Is the teaspoon per hours to metric cup per millisecond conversion exact?
Yes. Both teaspoon per hours and metric cup per millisecond are defined by fixed standards rather than physical artifacts, so the factor of 5.47658e-9 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.
