How to convert mass flow rate
Mass flow rate is how much mass passes a point per unit of time. It is used for steam, fuel, air and process materials.
Every mass flow rate unit is a fixed multiple of one base unit, the kg/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 lb/h to kg/h, multiply by 0.4535923700. To go the other way, divide by 0.4535923700.
The converter above does this for you and shows the exact formula under the result.
