An equivalent to 20 psi (pounds per square inch) can be expressed in several different units. For example, 20 psi is approximately 138 kilopascals (kPa) or 0.14 megapascals (MPa). In terms of atmospheric pressure, it is roughly 1.36 times the atmospheric pressure at sea level, which is about 14.7 psi.
