About Converting Quarts per Millisecond to Teaspoon per Hours
Quart per Millisecond and Teaspoon per Hours 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 hours = quarts per millisecond × 691200000
This factor comes from each unit's defined relationship to the category's base unit: 1 quart per millisecond equals 0.946352946 base units, and 1 teaspoon per hours equals 1.369145e-9 base units, so dividing one by the other gives the direct quart per millisecond-to-teaspoon per hours factor of 691200000.
Simple example
1 qt/ms × 691200000 = 691,200,000 tsp/h
1 quart per millisecond = 691,200,000 teaspoon per hours.
Real-world example
60 qt/ms × 691200000 = 41,472,000,000 tsp/h
60 quarts per millisecond = 41,472,000,000 teaspoon per hours.
Conversion table

Reverse conversion: Teaspoon per Hours to Quart per Millisecond
1 tsp/h × 1.446759e-9 = 1.446759e-9 qt/ms
1 teaspoon per hours = 1.446759e-9 quarts per millisecond.
quarts per millisecond = teaspoon per hours × 1.446759e-9

Frequently asked questions
How many teaspoon per hours are in 1 quart per millisecond?
1 quart per millisecond equals 691,200,000 teaspoon per hours, using the exact defined conversion factor rather than an estimate.
How do I convert quart per millisecond to teaspoon per hours?
Multiply the quart per millisecond value by 691200000. The converter above does this instantly to whatever precision you set.
How do I convert teaspoon per hours back to quart per millisecond?
Use the reverse factor: 1 teaspoon per hours equals 1.446759e-9 quarts per millisecond. You can also use the swap control in the converter above to flip the direction instantly.
What is a quart per millisecond?
Quart per Millisecond (qt/ms) is a unit of flow rate.
What is a teaspoon per hours?
Teaspoon per Hours (tsp/h) is a unit of flow rate.
Is the quart per millisecond to teaspoon per hours conversion exact?
Yes. Both quart per millisecond and teaspoon per hours are defined by fixed standards rather than physical artifacts, so the factor of 691200000 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.
