This converter allows you to convert bar [bar] to psi [psi] or psi [psi] to bar [bar]. Calculations are performed in both directions. The calculation result and the entered value are displayed with up to 20 decimal places for maximum accuracy.

1 bar [bar] ≈ 14.5038 psi [psi]1 psi [psi] ≈ 0.0689 bar [bar]

Convert bar to psi

There are two simple ways to convert bar [bar] to psi [psi]. In the first calculation method, the value in bar [bar] is divided by the rounded conversion factor of 0.0689. The second method multiplies the value in bar [bar] by the rounded conversion factor of 14.5038.

  • Psi [psi] ≈ bar [bar] ÷ 0.0689
  • Psi [psi] ≈ bar [bar] * 14.5038

However, rounded conversion values are only suitable for rough conversions, as rounding errors can occur in the calculation result. The most accurate conversion of bar [bar] to psi [psi] can be achieved using the following calculation method.

  • Psi [psi] = bar [bar] ÷ 4.5359237 ÷ 9.80665 * 645.16

Convert psi to bar

Converting psi [psi] to bar [bar] is easy and can be done in two ways. The first method involves multiplication, in which the value in psi [psi] is multiplied by the rounded conversion factor of 0.0689. The second variant is a division. Here, the value in psi [psi] is divided by the rounded conversion factor of 14.5038.

  • Bar [bar] ≈ psi [psi] * 0.0689
  • Bar [bar] ≈ psi [psi] ÷ 14.5038

However, rounded conversion values do not allow for exact calculations because rounding errors can occur in the calculation result. The most accurate conversion of psi [psi] to bar [bar] can be achieved using the following calculation method.

  • Bar [bar] = psi [psi] * 4.5359237 * 9.80665 ÷ 645.16
