Convert gradian to radian

Gradians and radians are units of angular measurement. Gradians, also known as grades or gon, divide a circle into 400 equal parts, whereas radians divide a circle into 2π (approximately 6.283) equal parts.

To convert gradians to radians, you can use the following formula:

radians = (gradians x π) / 200

where π (pi) is a mathematical constant that represents the ratio of the circumference of a circle to its diameter, approximately equal to 3.14159.

For example, if you have an angle of 50 gradians, the conversion to radians would be:

radians = (50 x π) / 200 radians = 0.7854

Therefore, 50 gradians is equal to 0.7854 radians (approximately).

Program Solution

//C Program 
//Convert gradian to radian
#include <stdio.h>

#include <math.h>

//Find the radian of given gradian
void gradian_to_radian(double gradian)
{
	// Formula : (gradian*π)/200
	// Calculate given gradian to radian 
	double radian = (gradian * M_PI) / 200;
	//Display result
	printf("Gradian : %lf  radian : %lf\n", gradian, radian);
}
int main()
{
	//Simple test
	gradian_to_radian(1);
	gradian_to_radian(50.80);
	gradian_to_radian(70.50);
	return 0;
}

Output

Gradian : 1.000000  radian : 0.015708
Gradian : 50.800000  radian : 0.797965
Gradian : 70.500000  radian : 1.107411
