PSI to Kilopascal Converter
Pressure · unit-converter
Convert PSI to Kilopascal 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 Kilopascal
The kilopascal (kPa) equals 1,000 Pa. It appears in HVAC, building science, and many technical specifications.
How to convert psi to kilopascal
1 psi equals 6.8947572931679995 kilopascal in this tool (via pascal):
1 psi = (6894.757293168 Pa ÷ 1000 Pa) kpa = 6.8947572931679995 kpa
Each psi carries 6894.757293168 Pa and each kilopascal 1000 Pa, so one psi equals 6894.757293168 ÷ 1000 kpa.
Let p(psi) be pressure in PSI (psi), and p(kpa) in Kilopascal (kpa). Then:
p(kpa) = p(psi) × (6894.757293168 / 1000)
Equivalently, divide by how many psi fit into one kpa (Pa per kpa divided by Pa per psi):
p(kpa) = p(psi) ÷ 0.14503773773021683
Examples
Example #1: Convert 1 psi to kilopascal
1 psi = 1 psi × (6894.757293168/1000) kpa = 6.8947572932 kpa
1 psi = 1 psi ÷ 0.14503773773021683 = 6.8947572932 kpa
1 psi × (6,894.757293168/1,000) = 6.894757 kpa
Example #2: Convert 10 psi to kilopascal
10 psi = 10 psi × (6894.757293168/1000) kpa = 68.9475729317 kpa
10 psi = 10 psi ÷ 0.14503773773021683 = 68.9475729317 kpa
10 psi × (6,894.757293168/1,000) = 68.947573 kpa
Summary
To convert PSI to Kilopascal, multiply the value in psi by (6894.757293168 Pa per psi) / (1000 Pa per kpa). Equivalently: value_kpa = value_psi × (6894.757293168 / 1000). Numerically, 1 psi equals 6.8947572931679995 kpa.
Relationship context
Both PSI and Kilopascal are converted by fixed multiples of the pascal. Multiplying by (Pa per psi) ÷ (Pa per kpa) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
