double area(double number, units from_unit, units to_unit)

Overview

The standard measurement units are:

Unit names	Alternate names / spellings	Abbreviation	Enumeration Code	Conversion Rate (relative to first unit)
Area
Meters2	Metres2	sq m	unit_m2	1
Acres	acre	a	unit_a	0.000247104
Feet2	foot2	sq ft	unit_ft2	10.76391042
Hectares	Hectare	ha	unit_ha	0.0001
Inches2	Inch2	sq in	unit_in2	1550.0031
Miles2	Mile2	sq mi	unit_mi2	3.86E-07

Example 1

#include <iostream>
#include <codecogs/units/convert/area.h>
using namespace Units::Convert;
int main()
{
  std::cout << "area(10.2,unit_m2, unit_ha)=" << area(10.2,unit_m2, unit_ha);

  return 0;
}

Output:

area(10.2,unit_m2, unit_ha)= 0.00102

Parameters

number

the value in from_unit 's to convert

from_unit

an enumerated value of the initial area type

to_unit

an emuerated value of the output area type

Returns
