How to convert kilomoles per hour to millimoles per second
Molar flow measures amount of substance. Converting to mass flow requires molar mass; converting to a gas volume flow also requires temperature, pressure, and a gas model.
Use x for the value in kmol/h, b for the intermediate value in mol/s, and y for the result in mmol/s.
mmol/s = kmol/h × 0.2777777777777778 ÷ 0.001
Worked examples
10 kmol/h ≈ 2777.77777778 mmol/s
Step 1: (10 × 0.277777777778) ≈ 2.77777777778 mol/s.
Step 2: 2.77777777778 ÷ 0.001 ≈ 2777.77777778 mmol/s.20 kmol/h ≈ 5555.55555556 mmol/s
Step 1: (20 × 0.277777777778) ≈ 5.55555555556 mol/s.
Step 2: 5.55555555556 ÷ 0.001 ≈ 5555.55555556 mmol/s.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilomoles per hour
Kilomoles per hour (kmol/h) measures flow molar under the conventions above. The base value in mol/s is (x × 0.277777777778), where x is the numerical value in kmol/h. Factors shown here are rounded for display; calculations use the stored factor.
About Millimoles per second
Millimoles per second (mmol/s) measures flow molar under the conventions above. The base value in mol/s is (x × 0.001), where x is the numerical value in mmol/s. Factors shown here are rounded for display; calculations use the stored factor.
