What Is This Tool?
This unit converter facilitates the transformation of molar flow rates from kilomol/hour (kmol/h), a measure representing thousands of moles per hour, into picomol/second (pmol/s), indicating extremely small amounts of substance per second. It is designed to help users translate chemical engineering or process flow data into precise microfluidic or analytical units.
How to Use This Tool?
-
Enter the molar flow value in kilomol/hour (kmol/h).
-
Select kilomol/hour as the input unit and picomol/second as the output unit.
-
Click the convert button to see the equivalent molar flow in picomol/second.
-
Use the converted value to assist with biochemical, microfluidic, or analytical calculations.

Assumes stable flow conditions and consistent unit standards.
-
Measurement sensitivities at low picomolar per second flows may affect practical accuracy.
Frequently Asked Questions
-
What does kilomol/hour measure?
-
Kilomol/hour measures the molar flow rate of a substance, indicating how many thousands of moles pass a point each hour.
-
Why convert kilomol/hour to picomol/second?
-
This conversion helps translate large-scale chemical process flow rates into very small flow rates needed for biochemical, microfluidic, or analytical applications.
-
Are there any considerations when converting between these units?
-
Yes, care must be taken with numerical precision, steady-state assumptions, and instrument limits especially at picomolar per second levels.
Key Terminology
-
Kilomol/hour [kmol/h]
-
A unit of molar flow rate equal to 1,000 moles passing a point each hour, used in chemical engineering and process calculations.
-
Picomol/second [pmol/s]
-
An SI-derived unit of molar flow representing 10^-12 moles passing a point every second, used for very low chemical or biochemical flow rates.
