What Is This Tool?
This unit converter facilitates the transformation of molar flow measurements expressed in picomol per second (pmol/s), representing very low flow rates, into mol per day (mol/d), a time-averaged rate used for daily reporting in scientific and industrial applications.
How to Use This Tool?
-
Enter the molar flow value in picomol/second (pmol/s) you wish to convert.
-
Select picomol/second as the input unit and mol/day as the output unit.
-
Click on the convert button to view the equivalent mol/day value.
-
Use the result for analysis, reporting, or process optimization.
Key Features
-
Converts molar flow from picomol/second to mol/day accurately using established conversion rates.
-
Supports applications in microfluidics, biochemical kinetics, environmental monitoring, and chemical engineering.
-
Browser-based tool that requires no installation, offering immediate results.
-
Enables easy interpretation of very small, precise molar flows in daily aggregated units.
Examples
-
Convert 10 pmol/s to mol/day: 10 × 8.64e-8 = 8.64e-7 mol/day.
-
Convert 100 pmol/s to mol/day: 100 × 8.64e-8 = 8.64e-6 mol/day.
Common Use Cases
-
Measuring reagent delivery rates in microfluidics and lab-on-chip devices at extremely low volumes.
-
Quantifying enzyme reaction rates and metabolic tracer fluxes in biochemical research.
-
Performing low-flow calibration and sensitivity checks for analytical instruments like mass spectrometers.
-
Reporting environmental fluxes such as daily emissions of CO2, methane, or nitrates from natural sources.
-
Evaluating daily production or consumption rates in fermenters and chemical reactors.
-
Preparing material balance and plant operational reports describing daily molar throughput.
Tips & Best Practices
-
Handle very small numeric results with care due to the low magnitude of picomol/second measurements.
-
Use consistent units throughout calculations to avoid errors in reporting.
-
Understand that mol/day provides averaged flow rates and does not capture intra-day fluctuations.
-
Verify that time integration methods align with your specific analytical or operational needs.
Limitations
-
Picomol/second units represent extremely low flow rates which may produce very small conversion results.
-
Mol/day is a non-SI unit mainly suited for aggregated daily averages rather than instantaneous measurements.
-
Instantaneous variations within the day are not reflected in the mol/day values.
-
Accurate unit consistency and time integration are important to prevent misinterpretation of data.
Frequently Asked Questions
-
What does one picomol/second represent?
-
One picomol/second represents a molar flow rate of 10^-12 moles passing a point every second, used for very small-scale chemical measurements.
-
Why convert picomol/second to mol/day?
-
Converting to mol/day translates tiny per-second molar flows into daily totals, facilitating reporting and comparison over longer time spans.
-
Is mol/day an SI unit?
-
No, mol/day is a derived non-SI unit that expresses molar flow averaged over a 24-hour period, commonly used in engineering and environmental applications.
Key Terminology
-
Picomol/second [pmol/s]
-
A SI derived unit for molar flow equal to 10^-12 moles passing a point each second, used to quantify very low flow rates.
-
Mol/day [mol/d]
-
A non-SI unit of molar flow indicating the amount of substance transferred or consumed per 24 hours; used for daily aggregate flows.
-
Molar flow
-
The rate at which moles of a substance pass through a given point per unit time.
