What Is This Tool?
This converter helps transform molar flow rates from picomol per second (pmol/s), which measures extremely small molecular flows common in biochemical and microfluidic contexts, to the standard mole per second (mol/s) unit widely used in chemical engineering and reaction kinetics.

Frequently Asked Questions
-
What does picomol per second measure?
-
Picomol per second (pmol/s) measures the rate of an amount of substance passing a point at a scale of 10^-12 moles per second, often used for very low flows in biochemical or microfluidic contexts.
-
Why convert pmol/s to mol/s?
-
Converting pmol/s to mol/s allows comparing very small flow rates to the standard SI unit mol/s, facilitating analysis across different scientific and engineering applications.
-
Can this tool be used for gas flow rates?
-
Yes, mol/s is used for quantifying gas flow rates in process equipment, so converting from pmol/s can support assessments involving gases at very low molar flows.
