You can't convert a RATIO (which is a pure number) to a MEASUREMENT such as psi. You get such a ratio by dividing two different pressures, for example.
A 1:1 ratio is equal to 0 PSI. 14.7 PSI is equal to a 2:1 ratio. Just multiply your ratio by 14.7 to get PSI, or divide PSI by 14.7 to get ratio. This is only in a perfect cylinder where valves close exactly as the piston reaches the bottom and stays closed the whole way, and if no air bleeds out from the valves, or between the piston and cylinder wall. Not to mention the difference between if it's hot or cold. Plus, according to the math problem, if you had a compression ratio of 1:1, you would be pushing 14.7 psi. So there isn't any REAL way of telling an engines compression ratio without getting the specs for everything.
23 psi = 1.6 bar
Multiply psi by 0.006894759086775369 to convert from psi to MPa. ex: 1000 psi = 1000 x 0.006894759086775369 = 6.89 MPa http://www.chapelsteel.com/psi-mpai.html
1885.5 PSI
Normal compression on a gasoline engine is about 125 psi.
200 psi
87 - 04 compression standard 121 psi minimum 114 psi max 128 psi
then youre running about 8.5:1 compression
"600 psi" is not a compression ratio; it's a pressure. For a RATIO, you need to compare TWO different numbers.
Engine compression psi? Radiator cap psi? Engine oil pressure psi? Tire pressure psi? Fuel pressure psi?
With a compression gauge.
100-125 psi
Tire psi? Engine compression psi? Radiator cap psi? Engine oil pressure psi?
i did the math and the exct commpression is 183.75 psi
Mine had about 80-110 psi
100 psi to 140 psi.
