# C Program to Convert Inches to Centimeters

In this article, we'll look at how to write a C program that asks the user for a length (in inches) and then converts and prints the equivalent length in centimeters. But before going through the program given below, let's first understand the relationship between an inch and a centimeter.

### Relationship between an inch and a centimeter

The relationship between an inch and a centimeter is written as:

1 centimeter = 0.3937 inches

or,

1 inch = 2.54 centimeters

**Note**: The spelling "centimetre" is used as international spelling, whereas "centimeter" is used as American spelling.

**Note**: A centimeter is equal to one hundredth of a meter.

A centimeter is represented by (cm), whereas an inch is represented by (" or in"). Therefore, we can write:

1^{"}= 2.54 cm

Now let's move on to the program.

## Converting inches to centimeters in C

The question is, "Write a program in C that converts length from inch to centimeter." The answer to this question is given below:

#include<stdio.h> #include<conio.h> int main() { float inch, cm; printf("Enter length in Inch: "); scanf("%f", &inch); cm = inch * 2.54; printf("Equivalent length in Centimeters = %0.2f", cm); getch(); return 0; }

As the above program was written in the Code::Blocks IDE, here is the snapshot of the sample run:

Now supply any length in inches, say 12, and press the ENTER key to see the same length in centimeters. Here is the second snapshot of the sample run:

Here are some of the main steps used in the above program:

- Receive any length in inches.
- 1 inch is equal to 2.54 cm.
- Therefore, to convert any length given in inches, we have to multiply it by 2.54 to convert it into centimeters.
- Print the length after converting to centimeters as output.
- Here we have used the format specifier of floating-point asĀ %0.2f to print the value up to its 2-decimal place.
