Bar to PSI Converter
Pressure · unit-converter
Convert Bar 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 Bar
The bar is 100,000 Pa. It is convenient for industrial and approximate atmospheric pressures (1 bar ≈ 1 atm).
About PSI
Pounds-force per square inch (PSI) is common for tires, hydraulics, and US industrial equipment.
How to convert bar to psi
1 bar equals 14.503773773021683 psi in this tool (via pascal):
1 bar = (100000 Pa ÷ 6894.757293168 Pa) psi = 14.503773773021683 psi
Each bar carries 100000 Pa and each psi 6894.757293168 Pa, so one bar equals 100000 ÷ 6894.757293168 psi.
Let p(bar) be pressure in Bar (bar), and p(psi) in PSI (psi). Then:
p(psi) = p(bar) × (100000 / 6894.757293168)
Equivalently, divide by how many bar fit into one psi (Pa per psi divided by Pa per bar):
p(psi) = p(bar) ÷ 0.06894757293168
Examples
Example #1: Convert 1 bar to psi
1 bar = 1 bar × (100000/6894.757293168) psi = 14.503773773 psi
1 bar = 1 bar ÷ 0.06894757293168 = 14.503773773 psi
1 bar × (100,000/6,894.757293168) = 14.503774 psi
Example #2: Convert 10 bar to psi
10 bar = 10 bar × (100000/6894.757293168) psi = 145.03773773 psi
10 bar = 10 bar ÷ 0.06894757293168 = 145.03773773 psi
10 bar × (100,000/6,894.757293168) = 145.037738 psi
Summary
To convert Bar to PSI, multiply the value in bar by (100000 Pa per bar) / (6894.757293168 Pa per psi). Equivalently: value_psi = value_bar × (100000 / 6894.757293168). Numerically, 1 bar equals 14.503773773021683 psi.
Relationship context
Both Bar and PSI are converted by fixed multiples of the pascal. Multiplying by (Pa per bar) ÷ (Pa per psi) gives the same result as passing through pascal, keeping bar, atm, PSI, kPa, hPa, torr, and mmHg consistent on the hub.
