FUNCTION

pressure

Converts a pressure from one unit to another.

Example 1

#include <iostream>
#include <codecogs/units/convert/pressure.h>

using namespace Units::Convert;
int main()
{
  std::cout << "pressure(23.5,unit_Pa, unit_T_ft2)=" << pressure(23.5,unit_Pa, unit_T_ft2);

  return 0;
}

Output:

pressure(23.5,unit_Pa, unit_T_ft2)= 0.00024540385232

Parameters

number

the value in from_unit 's to convert

from_unit

an enumerated value of the initial pressure type

to_unit

an emuerated value of the output pressure type

Returns

the value in the converted unit.
