About Converting Metric teaspoon per Seconds to Milliliter per Hours
Metric teaspoon per Seconds and Milliliter 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
milliliter per hours = metric teaspoon per seconds × 18000
This factor comes from each unit's defined relationship to the category's base unit: 1 metric teaspoon per seconds equals 0.000005 base units, and 1 milliliter per hours equals 2.777778e-10 base units, so dividing one by the other gives the direct metric teaspoon per seconds-to-milliliter per hours factor of 18000.
Simple example
1 metric tsp/s × 18000 = 18,000 mL/h
1 metric teaspoon per seconds = 18,000 milliliter per hours.
Real-world example
60 metric tsp/s × 18000 = 1,080,000 mL/h
60 metric teaspoon per seconds = 1,080,000 milliliter per hours.

Frequently asked questions
How many milliliter per hours are in 1 metric teaspoon per seconds?
1 metric teaspoon per seconds equals 18,000 milliliter per hours, using the exact defined conversion factor rather than an estimate.
How do I convert metric teaspoon per seconds to milliliter per hours?
Multiply the metric teaspoon per seconds value by 18000. The converter above does this instantly to whatever precision you set.
How do I convert milliliter per hours back to metric teaspoon per seconds?
Use the reverse factor: 1 milliliter per hours equals 0.0000555556 metric teaspoon per seconds. You can also use the swap control in the converter above to flip the direction instantly.
What is a metric teaspoon per seconds?
Metric teaspoon per Seconds (metric tsp/s) is a unit of flow rate.
What is a milliliter per hours?
Milliliter per Hours (mL/h) is a unit of flow rate.
Is the metric teaspoon per seconds to milliliter per hours conversion exact?
Yes. Both metric teaspoon per seconds and milliliter per hours are defined by fixed standards rather than physical artifacts, so the factor of 18000 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.
