Pa to psi · pressure conversion
What are pascals and pounds per square inch?
The pascal is the SI unit of pressure, one newton per square meter. Pounds per square inch is the imperial pressure unit, standard for US tires and plumbing. For reference: car tires run around 32 psi (220 kPa), and sea-level air pressure is about 101 kPa.
How to convert pascals to pounds per square inch
1 Pa = 0.000145038 psi. To convert, multiply the number of pascals by 0.000145038. For example, 5 Pa = 0.000725189 psi, and 20 Pa = 0.00290075 psi. To go the other way, multiply pounds per square inch by 6,894.76 (since 1 psi = 6,894.76 Pa).
