Program to Convert Centimeter to Feet and Inches in C

Given with the length in centimeters as an input, the task is to convert the given length into feet and inches using C programming.

We can use length conversion formulas for this −

1 feet = 30.48 cm
1 inch = 2.54 cm

Syntax

double inches = centimeters * 0.3937;
double feet = centimeters * 0.0328;

Algorithm

Start
Step 1 ? Declare function to perform conversion
   double convert(int centimeter)
      set double inch = 0.3937 * centimeter
      set double feet = 0.0328 * centimeter
      print inch and feet
Step 2 ? In main()
   Declare and set int centimeter = 20
   Call convert(centimeter)
Stop

Example

Here's a complete program to convert centimeters to feet and inches −

#include <stdio.h>

// Function to perform conversion
void convert(int centimeter) {
    double inch = 0.3937 * centimeter;
    double feet = 0.0328 * centimeter;
    printf("Centimeters: %d<br>", centimeter);
    printf("Inches: %.2f<br>", inch);
    printf("Feet: %.2f<br>", feet);
}

// Driver Code
int main() {
    int centimeter = 100;
    convert(centimeter);
    return 0;
}

Output

Centimeters: 100
Inches: 39.37
Feet: 3.28

Example 2: Converting to Feet and Remaining Inches

This approach shows conversion to feet with remaining inches displayed separately −

#include <stdio.h>

void convertToFeetInches(int centimeters) {
    // Convert to total inches first
    double totalInches = centimeters * 0.3937;
    
    // Extract feet and remaining inches
    int feet = (int)(totalInches / 12);
    double remainingInches = totalInches - (feet * 12);
    
    printf("Centimeters: %d<br>", centimeters);
    printf("Conversion: %d feet and %.2f inches<br>", feet, remainingInches);
}

int main() {
    int centimeters = 152;
    convertToFeetInches(centimeters);
    return 0;
}

Output

Centimeters: 152
Conversion: 4 feet and 11.84 inches

Conclusion

Converting centimeters to feet and inches in C involves simple multiplication with conversion factors. The first method gives separate decimal values, while the second shows practical feet-inches format commonly used in measurements.
