Multiply bar by 14.50377377. The calculator applies this relationship immediately and supports positive, negative, and decimal values where appropriate.
This conversion is commonly useful for tire pressure, compressors, hydraulics, and industrial equipment.
| bar | psi |
|---|---|
| 1 bar | 14.50377377 psi |
| 5 bar | 72.51886885 psi |
| 10 bar | 145.0377377 psi |
| 25 bar | 362.59434425 psi |
| 100 bar | 1450.377377 psi |
For 10 bar, multiply 10 by 14.50377377. The result is 145.0377377 psi.

Yes. Enter any decimal value and the result updates automatically.
Pressure is force distributed over area. Units such as pascal, kilopascal, bar, and pounds per square inch express the same physical quantity using different scales. This calculator converts the numeric reading only; it does not adjust gauge pressure to absolute pressure or account for altitude and temperature.
Check whether an instrument reports gauge pressure or absolute pressure before comparing readings. Tire, hydraulic, weather, and laboratory applications can use different conventions and tolerances. Safety-critical equipment should always be set and verified using the manufacturer’s specifications and a calibrated instrument.
The calculation runs locally in your browser: the number you enter is multiplied or divided using the stated factor, and the result is formatted for readability. Convertly does not send calculator entries to a server. We preserve more precision internally than is normally useful on screen, so you can enter decimals without the calculator repeatedly rounding intermediate values.
Reviewed: September 3, 2026. Conversion relationships are checked against recognized measurement definitions, including the International System of Units and U.S. National Institute of Standards and Technology measurement guidance. Read our calculation methodology and source policy for definitions, rounding rules, limitations, and correction procedures.
Before converting, confirm that the input unit matches the value you have and that the output unit is the one required. Enter the unrounded source value whenever possible. After calculating, choose a sensible number of decimal places for the task rather than copying every digit automatically.
A useful cross-check is to estimate the direction and approximate size of the answer. Converting to a smaller unit usually produces a larger number; converting to a larger unit usually produces a smaller number. If the result differs greatly from that expectation, check for a misplaced decimal, a confused unit abbreviation, or the reverse conversion. The formula and worked example on this page are provided so the result can be independently checked.
