convert

Converts numbers from one unit to another. This module acts as a unit converter, converting approximately 150 different units (see below).

This module is similar to the EXCEL convert function, only considerably smarter. Converts a number from one measurement system to another. For example, convert can translate a distance in miles to meters. There is a check that the requested input and output units are compatable i.e. it will not allow a length to be converted into a pressure.

#include <iostream>
#include <codecogs/units/convert/convert.h>
using namespace Units;
int main()
{
  std::cout << "convert(10.2,unit_m, unit_ft)=" <<convert(10.2,unit_m, unit_ft);
  std::cout << "convert(123, unit_W, unit_HP)=" <<convert(123, unit_W, unit_hp);

  return 0;
}

convert(10.2,unit_m, unit_ft)= 33.46456693
  convert(123, unit_W, unit_HP)= 0.013678405

Parameters

Returns

Conversion between incompatible types will throw an error

This function attempts to recognise the unit within a character string. The function scans through a list of variable names and computes the percentage match. It returns the variable with the highest match, i.e. the closest unit to the string specified.

See:

Used by convert to recognises each of the two input strings.

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

int main()
{
   std::cout << "convert(10.2,\"meters\", \"feet\")=" << Units::convert(10.2,"meters", "feet");
   std::cout << "convert(123, \"W\", \"Horce power\")=" << Units::convert(123, "W", "Horce power");
   
   return 0;
}

convert(10.2,"meters", "feet")= 33.46456693
  convert(123, "W", "Horce power")= 0.013678405

Parameters

Recognises the power token for SI units within in a text string

Parameters

Returns

Recognised the units within two character strings and converts the given number from one unit ito another. This routine tries to find the optimal match by calculating the most likely set of units from given text strings. To improve the matching, it is important that the initial spelling of the unit is correct (first 3-4 characters). The importance of subsequent letters becomes increasingly irrelevent.

Parameters

Returns

Conversion between incompatible types will return 0.
