Convert hectare to square kilometer

A hectare is a unit of area that is commonly used to measure land, particularly in agriculture and forestry. It is equal to 10,000 square meters.

A square kilometer, on the other hand, is a unit of area that is equal to 1,000,000 square meters.

To convert hectares to square kilometers, you can divide the number of hectares by 100. For example, if you have 500 hectares of land, the conversion would be:

500 hectares ÷ 100 = 5 square kilometers

Therefore, 500 hectares of land is equivalent to 5 square kilometers of land.

Code Solution

//C Program 
//Convert hectare to square kilometer
#include <stdio.h>
 //Find the square kilometer of given hectare
void hectare_to_square_km(double hectare)
{
	// Calculate square kilometer by using hectare
	// Formula : (hectare / 100)
	double square_km = (hectare / 100);
	printf("[%lf] Hectare is equal to [%lf] Square Kilometer \n", hectare, square_km);
}
int main()
{
	//Simple test
	hectare_to_square_km(1);
	hectare_to_square_km(2021);
	hectare_to_square_km(1500.6);
	return 0;
}

Output

[1.000000] Hectare is equal to [0.010000] Square Kilometer
[2021.000000] Hectare is equal to [20.210000] Square Kilometer
[1500.600000] Hectare is equal to [15.006000] Square Kilometer
