Full precision:0.13368 CFM
Step-by-Step Solution
To convert 1 gpm to cfm, we divide by 7.4805 because one cubic foot per minute equals exactly 7.4805 gpm.
1 cubic foot per minute = 7.4805 gpm
Since there are 7.4805 gpm in every cubic foot per minute, we divide our value by this factor:
1 ÷ 7.4805 = 0.13368 cfm
So 1 gpm = 0.13368 cfm.
Quick check: 0.13368 × 7.4805 = 1 gpm
Example Conversions
Example 1: 1 GPM = 0.13368 CFM
1 ÷ 7.4805 = 0.13368
1 ÷ 7.4805 = 0.13368
Example 2: 5 GPM = 0.6684 CFM
5 ÷ 7.4805 = 0.6684
5 ÷ 7.4805 = 0.6684
Example 3: 10 GPM = 1.3368 CFM
10 ÷ 7.4805 = 1.3368
10 ÷ 7.4805 = 1.3368
