Conversion of bar
In order to convert bar [bar] 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 bar [bar] to be queried directly from the conversion table.
Determine conversion factor
Conversion between bar and millibar
A quick and precise conversion between bar [bar] and millibar [mbar] is straightforward and requires only multiplication or division by 1,000. The conversion from bar [bar] to millibar [mbar] is done by multiplying the value in bar [bar] by 1,000. To reverse the conversion, divide the value in millibar [mbar] by 1,000 to obtain bar [bar].
- Millibar [mbar] = bar [bar] * 1,000
- Bar [bar] = millibar [mbar] ÷ 1,000
Conversion between bar and psi
You can easily convert between bar [bar] and psi [psi] using the formulas provided below. For accurate results, it is important to follow the correct order of mathematical operations.
- Psi [psi] = bar [bar] ÷ 4.5359237 ÷ 9.80665 * 645.16
- Bar [bar] = psi [psi] * 4.5359237 * 9.80665 ÷ 645.16
Conversion between bar and pascals
Conversions between bar [bar] and pascals [Pa] are straightforward and can be performed with simple math. The required conversion factor is 100,000. To convert a value from bar [bar] to pascals [Pa], multiply the number of bar [bar] by 100,000. For values in pascals [Pa], divide by 100,000 to get the equivalent in bar [bar].
- Pascals [Pa] = bar [bar] * 100,000
- Bar [bar] = pascals [Pa] ÷ 100,000
Conversion between bar and kilograms per square meter
The fastest and easiest way to convert between bar [bar] and kilograms per square meter [kg/m²] is to use the converter above. Manual conversions are also possible and can be done using the formulas provided below.
- Kilograms per square meter [kg/m²] = bar [bar] ÷ 9.80665 * 105
- Bar [bar] = kilograms per square meter [kg/m²] * 9.80665 ÷ 105
Conversion between bar and metric tons per square meter
The two formulas below provide an easy way to convert between bar [bar] and metric tons per square meter [t/m²]. To ensure precise conversion results, it is important to follow the correct order of math operations.
- Metric tons per square meter [t/m²] = bar [bar] ÷ 9,806.65 * 105
- Bar [bar] = metric tons per square meter [t/m²] * 9,806.65 ÷ 105
