Conversion of psi
In order to convert 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 to be queried directly from the conversion table.

Conversion between psi and millibar
You can easily convert between millibar [mbar] and psi using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Psi = millibar [mbar] ÷ 453.59237 ÷ 9.80665 * 64,516 ÷ 103
- Millibar [mbar] = psi * 453.59237 * 9.80665 ÷ 64,516 * 103
Conversion between psi and bar
The fastest and easiest way to convert between bar and psi is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Psi = bar ÷ 4.5359237 ÷ 9.80665 * 645.16
- Bar = 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. To ensure precise conversion results, it is important to follow the correct order of math operations.
- Psi = pascals [Pa] ÷ 453.59237 ÷ 980,665 * 64,516
- Pascals [Pa] = psi * 453.59237 * 980,665 ÷ 64,516
Conversion between psi and kilograms per square meter
You can easily convert between 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 * 4,535.9237 ÷ 6.4516
- 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 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 ÷ 56.038 ÷ 1,129.03 * 4,535.9237 * 9.80665
- Psi = metric tons per square meter [t/m²] * 56.038 * 1,129.03 ÷ 4,535.9237 ÷ 9.80665
