+
+- This simple program converts between different common units of pressure such as
+Pascal(Pa),Bar(bar),Millimeter Mercury(mmHg) and atmosphere(atm).
+the test cases are based on the fact that the value of pressure
+on it's own can never be negative,except in cases where it is relative to another kind of pressure.
+
+- Run the doctest via the command
+
+```
+$ python -m doctest -v Pressure_Converter/pressure_converter_script.py
+```
