Kilopascal to PSI Converter
Pressure · unit-converter
Convert Kilopascal to PSI 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 Kilopascal
The kilopascal (kPa) equals 1,000 Pa. It appears in HVAC, building science, and many technical specifications.
About PSI
Pounds-force per square inch (PSI) is common for tires, hydraulics, and US industrial equipment.
How to convert kilopascal to psi
1 kilopascal equals 0.14503773773021683 psi in this tool (via pascal):
1 kpa = (1000 Pa ÷ 6894.757293168 Pa) psi = 0.14503773773021683 psi
Each kilopascal carries 1000 Pa and each psi 6894.757293168 Pa, so one kpa equals 1000 ÷ 6894.757293168 psi.
Let p(kpa) be pressure in Kilopascal (kpa), and p(psi) in PSI (psi). Then:
p(psi) = p(kpa) × (1000 / 6894.757293168)
Equivalently, divide by how many kpa fit into one psi (Pa per psi divided by Pa per kpa):
p(psi) = p(kpa) ÷ 6.8947572931679995
Examples
Example #1: Convert 1 kpa to psi
1 kpa = 1 kpa × (1000/6894.757293168) psi = 0.1450377377 psi
1 kpa = 1 kpa ÷ 6.8947572931679995 = 0.1450377377 psi
1 kpa × (1,000/6,894.757293168) = 0.145038 psi
Example #2: Convert 10 kpa to psi
10 kpa = 10 kpa × (1000/6894.757293168) psi = 1.4503773773 psi
10 kpa = 10 kpa ÷ 6.8947572931679995 = 1.4503773773 psi
10 kpa × (1,000/6,894.757293168) = 1.450377 psi
Summary
To convert Kilopascal to PSI, multiply the value in kpa by (1000 Pa per kpa) / (6894.757293168 Pa per psi). Equivalently: value_psi = value_kpa × (1000 / 6894.757293168). Numerically, 1 kpa equals 0.14503773773021683 psi.
Relationship context
Both Kilopascal and PSI are converted by fixed multiples of the pascal. Multiplying by (Pa per kpa) ÷ (Pa per psi) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
