Millimole per Minute (mmol/min)
Definition: A molar flow unit for millimoles passing a point per minute, matching typical laboratory syringe-pump and peristaltic-pump feed rates.
History: Reflects laboratory equipment convention, where syringe pumps and dosing instruments are commonly calibrated and displayed in per-minute terms.
Current use: Frequently used to specify laboratory syringe pump and dosing pump molar delivery rates in flow chemistry and biochemistry.
Kilomole per Day (kmol/d)
Definition: A molar flow unit for kilomoles passing a point per day, used for reporting cumulative daily throughput of a continuous chemical process.
History: Developed as plant management and regulatory reporting shifted toward daily production and emissions summaries alongside the finer-grained hourly process data.
Current use: Used in daily production summaries, environmental permit reporting, and capacity planning for continuous chemical and gas-processing facilities.

About These Parameters
- Value
- The molar flow rate value you want to convert, expressed in the "From" unit. Accepts decimals.
- From Unit
- The unit your input value is currently measured in — a reactor feed spec's mol/s, or a plant mass-balance sheet's kmol/h.
- To Unit
- The unit you want the result converted into. Use the swap button to flip From and To instantly.
How Flow - Molar Conversion Works
The Formula
Every unit here is defined by a fixed multiplier relative to moles per second. To convert a value from one unit to another:
result = value × (factor of "From" unit ÷ factor of "To" unit)
For Millimole per Minute → Kilomole per Day: multiply by 0.0014400029. For example, 1 mmol/min × 0.0014400029 = 0.0014400029 kmol/d.
Molar Flow vs. Mass Flow
This site's separate Flow - Mass Converter measures how much MASS (kilograms, pounds) passes a point per unit time, while this page measures how many MOLES pass instead. The two are related by molar flow = mass flow ÷ molar mass of the substance — but that conversion requires knowing exactly which gas or fluid is flowing, since every substance has a different molar mass (water is about 18 g/mol, while carbon dioxide is about 44 g/mol). Because of that substance-dependence, molar flow and mass flow can't be converted with a fixed multiplier the way the units on this page can — you always need the specific compound's molar mass as an extra input.
Why Moles Matter in Process Engineering
Balanced chemical equations are written in mole ratios — one mole of methane reacts with two moles of oxygen, for instance — so reactor mass balances, catalyst dosing, and conversion/yield calculations are all naturally done in moles rather than mass or volume. Molar flow also plugs directly into the ideal gas law (PV = nRT), letting engineers relate a gas stream's molar flow rate to its pressure, volume, and temperature without any substance-specific density lookup. This is why process flow diagrams and reactor design calculations almost always carry a molar flow rate figure alongside, or instead of, a mass or volumetric flow rate.
Example
A molar flow rate of 1 mmol/min equals 0.0014400029 kmol/d. For scale, a small laboratory continuous-flow reactor might run at only a few mmol/s, while a full-scale industrial ammonia synthesis reactor can process feed gas at hundreds of kmol/h.
Frequently Asked Questions
How many Kilomoles per Day are in 1 Millimole per Minute?
1 Millimole per Minute (mmol/min) equals exactly 0.0014400029 Kilomoles per Day (kmol/d).
What is molar flow rate used for?
Molar flow rate is used throughout chemical engineering to size reactors, calculate reaction conversion and yield, balance mass across a process, and apply the ideal gas law to gas streams — anywhere a calculation depends on the number of reacting particles rather than their mass or volume.
How do I convert molar flow to mass flow?
Multiply the molar flow rate by the substance's molar mass: mass flow = molar flow × molar mass. For example, 10 mol/s of water (molar mass 18.015 g/mol) is a mass flow of about 180.15 g/s. This site's units page can't do that step for you since it requires knowing which specific substance is flowing — use the site's separate Flow - Mass Converter once you have the mass figure.
How accurate are these conversions?
Every conversion factor used here is an exact, fixed multiplier relative to moles per second (a simple ratio of time-unit and metric-prefix scaling) — results are limited only by floating-point display precision, not by rounded conversion constants.
