The Psi Converter supports 31 different pressure units. This makes it possible to convert freely between psi [psi], American, metric, and other pressure units. All values are converted in real time and displayed with up to 20 decimal places, ensuring sufficient accuracy.


Conversion of psi

In order to convert psi [psi] into another printing unit, a conversion value is required. This value can be determined using a conversion table. However, the table is relatively large, confusing, and difficult for inexperienced users to understand. The tool below provides a solution to this problem by allowing the rounded conversion values for psi [psi] to be queried directly from the conversion table.

Determine conversion factor

≈ 14.5038
Calculation example:
Bar = Psi * 4.5359237 * 9.80665 ÷ 645.16
Psi = Bar ÷ 4.5359237 ÷ 9.80665 * 645.16

Conversion between psi and millibar

You can easily convert between millibar [mbar] and psi [psi] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.

  • Psi [psi] = millibar [mbar] ÷ 453.59237 ÷ 9.80665 * 64,516 ÷ 103
  • Millibar [mbar] = psi [psi] * 453.59237 * 9.80665 ÷ 64,516 * 103

Conversion between psi and bar

The fastest and easiest way to convert between bar [bar] and psi [psi] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.

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

Conversion between psi and pascals

The two formulas below provide an easy way to convert between pascals [Pa] and psi [psi]. To ensure precise conversion results, it is important to follow the correct order of math operations.

  • Psi [psi] = pascals [Pa] ÷ 453.59237 ÷ 980,665 * 64,516
  • Pascals [Pa] = psi [psi] * 453.59237 * 980,665 ÷ 64,516

Conversion between psi and kilograms per square meter

You can easily convert between psi [psi] and kilograms per square meter [kg/m²] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.

  • Kilograms per square meter [kg/m²] = psi [psi] * 4,535.9237 ÷ 6.4516
  • Psi [psi] = kilograms per square meter [kg/m²] ÷ 4,535.9237 * 6.4516

Conversion between psi and metric tons per square meter

The fastest and easiest way to convert between psi [psi] and metric tons per square meter [t/m²] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.

  • Metric tons per square meter [t/m²] = psi [psi] ÷ 56.038 ÷ 1,129.03 * 4,535.9237 * 9.80665
  • Psi [psi] = metric tons per square meter [t/m²] * 56.038 * 1,129.03 ÷ 4,535.9237 ÷ 9.80665
