Engineers and others working with fluid transport systems can choose from a wide variety of units to describe the flow rate of liquids. One common unit based on the metric system is cubic meters per hour (m3/h) which is a measure of the volume of liquid, in cubic meters, which flows through a pipe each hour. Another measure of flow, which is non-metric, is gallons per minute (gpm). You can convert from m3/h to gpm using a single conversion factor.
Things You'll Need
Enter the value of the fluid flow rate, in units of m3/h, into the calculator. For example, if you had a hose which was expelling water at a rate of 50 m3/h, you would enter 50.
Multiply the value you just entered by 4.403. This is the conversion factor between m3/h and gpm.
Report the result of your calculation as the fluid flow rate in units of gpm. In the case of the example, you would calculate 50 times 4.403 and obtain a result of 220 gpm.
Tips & Warnings
- The conversion factor in this procedure is for U.S. gallons.
