how many centimeters are in an inch

To convert inches to centimeters, we will use the conversion factor of 2.54 centimeters per inch. This means that there are 2.54 centimeters in every inch.

Step 1: Determine the number of inches to be converted. Let’s say we have 5 inches.

Step 2: Multiply the number of inches by the conversion factor of 2.54 centimeters per inch. This will give us the equivalent value in centimeters.

5 inches * 2.54 centimeters / 1 inch = 12.7 centimeters

Step 3: Now, we have our answer in centimeters, which is 12.7 centimeters. We can also write this as a ratio to show the conversion.

5 inches : 12.7 centimeters

Step 4: If we want to convert a larger or smaller value, we can use the same method. For example, if we have 10 inches, the conversion would be:

10 inches * 2.54 centimeters / 1 inch = 25.4 centimeters

10 inches : 25.4 centimeters

Step 5: If we want to convert from centimeters to inches, we can use the inverse of the conversion factor, which is 1 inch per 2.54 centimeters. Therefore, the steps would be:

1) Determine the number of centimeters to be converted
2) Multiply the number of centimeters by the conversion factor of 1 inch per 2.54 centimeters
3) The answer will be in inches.

For example, if we have 20 centimeters:

20 centimeters * 1 inch / 2.54 centimeters = 7.87 inches

20 centimeters : 7.87 inches

By following these steps, any value in inches can be converted to centimeters and vice versa. Remember to round your answer to the appropriate number of significant figures based on the given values.
