PSI to Pascal Converter
Pressure · unit-converter
Convert PSI to Pascal with a fixed input and output unit, step-by-step formula line, and reference tables. All calculations bridge through pascal with fixed definitions (standard atmosphere = 101,325 Pa; torr and mmHg = atm/760; plus industrial/manometer units like kgf/cm², inHg, inH2O, and mmH2O).
About PSI
Pounds-force per square inch (PSI) is common for tires, hydraulics, and US industrial equipment.
About Pascal
The pascal (Pa) is the SI unit of pressure (one newton per square meter). It is the common reference for scientific and engineering work.
How to convert psi to pascal
1 psi equals 6894.757293168 pascal in this tool (via pascal):
1 psi = (6894.757293168 Pa ÷ 1 Pa) pa = 6894.757293168 pa
Each psi carries 6894.757293168 Pa and each pascal 1 Pa, so one psi equals 6894.757293168 ÷ 1 pa.
Let p(psi) be pressure in PSI (psi), and p(pa) in Pascal (pa). Then:
p(pa) = p(psi) × (6894.757293168 / 1)
Equivalently, divide by how many psi fit into one pa (Pa per pa divided by Pa per psi):
p(pa) = p(psi) ÷ 0.00014503773773021683
Examples
Example #1: Convert 1 psi to pascal
1 psi = 1 psi × (6894.757293168/1) pa = 6894.75729317 pa
1 psi = 1 psi ÷ 0.00014503773773021683 = 6894.75729317 pa
1 psi × (6,894.757293168/1) = 6,894.757293 pa
Example #2: Convert 10 psi to pascal
10 psi = 10 psi × (6894.757293168/1) pa = 68947.5729317 pa
10 psi = 10 psi ÷ 0.00014503773773021683 = 68947.5729317 pa
10 psi × (6,894.757293168/1) = 68,947.572932 pa
Summary
To convert PSI to Pascal, multiply the value in psi by (6894.757293168 Pa per psi) / (1 Pa per pa). Equivalently: value_pa = value_psi × (6894.757293168 / 1). Numerically, 1 psi equals 6894.757293168 pa.
Relationship context
Both PSI and Pascal are converted by fixed multiples of the pascal. Multiplying by (Pa per psi) ÷ (Pa per pa) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
