Pint per minute (P/min) is a unit of volumetric flow rate, representing the volume of liquid flowing through a given area in a minute. It is often used in various industries, including chemical processing, oil and gas, and food production, to measure the flow rate of liquids. To convert Pint per minute to Litre per hour (L/h), we multiply the flow rate by 60 (to convert minutes to hours) and then by 568.261 (since 1 pint is approximately equal to 568.261 millilitres or 0.568261 litres). This conversion is essential in scientific and industrial applications where precise measurement of liquid flow rates is critical.
