* Added physical pressure units This uses tuple pair which stores units required to be converted to respective other units as mentioned. Available Units:- Pascal,Bar,Kilopascal,Megapascal,psi(pound per square inch),inHg(in mercury column),torr,atm * Formatted file File was formatted as per repo rules * Reformatted file :) * Added more reference * More reference added

Conversion of pressure units.
|
|
Available Units:- Pascal,Bar,Kilopascal,Megapascal,psi(pound per square inch),
|
|
inHg(in mercury column),torr,atm
|
|
USAGE :
|
|
-> Import this file into their respective project.
|
|
-> Use the function pressure_conversion() for conversion of pressure units.
|
|
-> Parameters :
|
|
-> value : The number of from units you want to convert
|
|
-> from_type : From which type you want to convert
|
|
-> to_type : To which type you want to convert
