How to Convert Millimol/hour to Mole/second

Converting Millimol/hour (mmol/h) to Mole/second (mol/s) is a core calculation in Molar Flow Rate, which measures the chemical amount of substance (in moles) flowing through a boundary per unit of time. Because Mole/second is a broader physical scale than Millimol/hour, converting from mmol/h to mol/s condenses the numerical figure. It takes 3600000 Millimol/hour to equal a single Mole/second (1 mmol/h = 2.777778 × 10⁻⁷ mol/s). To convert any quantity, multiply by 2.777778 × 10⁻⁷ (or divide by 3600000).

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (mole per second (mol/s)) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)
Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)
1. Source SI Bridge (ksource):1 mmol/h = 2.777778 × 10⁻⁷ mole per second (mol/s)
2. Target SI Bridge (ktarget):1 mol/s = 1 mole per second (mol/s)
Step-by-step substitution for Millimol/hour → Mole/second:V(mol/s) = V(mmol/h) × ( 2.777778 × 10⁻⁷ / 1 ) = V(mmol/h) × 2.777778 × 10⁻⁷
Mathematical FormulaValue in Mole/second = Value in Millimol/hour × 2.77777778 × 10⁻⁷Direct computational formula applied for standard conversion.
Worked Example

Evaluating an input of 12 Millimol/hour (mmol/h) produces 3.333333 × 10⁻⁶ Mole/second (mol/s). In heavy-duty utility and industrial workloads, 1000 mmol/h equals 0.000277778 mol/s.

Inverse check: 1 mol/s = 3600000 mmol/h.
