Converting units of pressure
The calculator converts standard units of pressure with a precision of two decimal places:
 bars (bar)
 nanobars (nbar)
 pascals (pascaly)
 hectopascals (hPa)
 millibars (mbar)
 kilopascals (kPa)
 megapascals (MPa)
Conversions therefore works from for example pascals to bars, kilopascals to milibars and all other combinations.
Calculator for converting units of pressure
You need to input these three values into the calculator:

Pressure that you want to convert

The unit from which you want to convert

The unit to which you want to convert
Explanation of conversions
In the table you can see how the individual unit conversions work.
From every standard unit to the nearest smaller and larger unit.
Table of standard units of pressure 
1 MPa

=  10 bar 
1 bar  =  100 kPa 
1 kPa  =  10 hPa 
1 kPa  =  10 mbar 
1 hPa  =  100 Pa 
1 mbar  =  100 Pa 
1 Pa  = 
10 000 nbar

1 nbar  =  0.0001 Pa 
1 Pa  =  0.01 hPa 
1 Pa  =  0.01 mbar 
1 hPa  =  0.1 kPa 
1 mbar  =  0.1 kPa 
1 kPa  =  0.01 bar 
1 bar  =  0.1 MPa 
Converting units of pressure questions and answers
When are bars as a unit used?
Bars are not an SI unit but are commonly used in meteorology.
How does the metric length system work?
The metric mass system is based on magnitude so the difference between pascals or kilopascals or megapascals is some power of 10.
