To calculate the pounds per square inch (psi) from the compression ratio, one needs the compression ratio and the atmospheric pressure measurement. Then, the first number in the compression ratio is multiplied by the atmospheric pressure, then divided by the second number in the ratio.
Know MoreFor example, if the atmospheric pressure is 14.7 psi and the compression ratio is 11:1, the equation to solve for the psi is (14.7*11)/1. Therefore, the answer is 161.7 psi. People use this method of calculation to determine the pounds per square a piston produces.
The atmospheric pressure can vary, but the standard atmosphere produces 14.696 psi at sea level. For more exact calculations, the altitude should be considered.

Full Answer >Converting kilograms to pounds requires multiplying the number of kilograms by 2.2 because 1 kilogram equals 2.2 pounds. To find out how many pounds a person weighing 100 kilograms is, multiply 100 by 2.2. The person weighs 220 pounds.
Full Answer >Converting from pounds to kilograms involves finding the conversion factor of 0.45 kilograms/pound and using this to create an equation. Solving the equation finds the metric equivalent, 62.1 kilograms, of 138 pounds.
Full Answer >Converting pounds to kilograms is dependent on the fact that each pound is made up of .454 kilograms. With this conversion rate, 95 pounds equals 43 kilograms.
