How to convert molar flow rate

Molar flow rate is the amount of substance (in moles) passing a point per unit of time. It is used in chemical engineering and reactor design.

Every molar flow rate unit is a fixed multiple of one base unit, the mol/s. To convert a value, multiply it by the size of the starting unit and divide by the size of the target unit. For example, to convert kmol/h to mol/s, multiply by 0.2777777778. To go the other way, divide by 0.2777777778.

The converter above does this for you and shows the exact formula under the result.

Worked examples

10 kmol/h = 2.7777778 mol/s10 × 0.2777777778 = 2.777777778 mol/s.
25 mol/s = 1,500.0000 mol/min25 × 60.00000000 = 1,500.000000 mol/min.

Frequently asked questions

How many mol/s is 1 kmol/h?

One kilomole per hour is about 0.2778 moles per second (1,000 ÷ 3,600).

How do I convert kmol/h to mol/s?

Multiply the value in kmol/h by 0.2777777778 to get mol/s. For example, 10 kmol/h = 2.777777778 mol/s.

How many mol/s is 1 kmol/h?

1 kmol/h = 0.2777777778 mol/s, and 1 mol/s = 3.600000000 kmol/h.
