Calculation Details

What are Inches and Centimeters?

Inches and centimeters are both units of measurement used to describe length or distance.


  • Used primarily in the United States and Canada.
  • Divided into 12 parts called twelfths of an inch, and further into 16 parts called sixteenths of an inch.
  • Commonly used for smaller measurements like the width of a ruler, the height of a person, or the diameter of a screw.


  • Part of the metric system, which is the predominant system of measurement used in most of the world.
  • Divided into 10 parts called millimeters, and further into 100 parts called tenths of a millimeter.
  • Typically used for longer measurements like the height of a building, the length of a car, or the distance between two cities.

Key Aspects of Inches and Centimeters


  • 1 inch is equal to 2.54 centimeters.
  • To convert inches to centimeters, multiply the number of inches by 2.54.
  • To convert centimeters to inches, divide the number of centimeters by 2.54.

Additional Points:

  • Some countries, like the United Kingdom, use a hybrid system with both inches and centimeters.
  • When converting, be mindful of rounding rules for accuracy.

All Formulae Inches to Centimeters Calculator

Here are the essential formulae and steps for converting between inches and centimeters:

1. To convert inches to centimeters:

  • Formula: centimeters = inches × 2.54
  • Explanation: Multiply the number of inches by 2.54, as there are 2.54 centimeters in 1 inch.

2. To convert centimeters to inches:

  • Formula: inches = centimeters / 2.54
  • Explanation: Divide the number of centimeters by 2.54 to get the equivalent value in inches.

3. Calculator:

  • You can easily perform these conversions using a calculator:
    • For inches to centimeters: Enter the number of inches, press the “×” button, and then enter 2.54.
    • For centimeters to inches: Enter the number of centimeters, press the “÷” button, and then enter 2.54.


  • 5 inches to centimeters: 5 × 2.54 = 12.7 centimeters
  • 20 centimeters to inches: 20 ÷ 2.54 = 7.874 inches (approximately)

Practical Uses of Inches and Centimeters

Both inches and centimeters have their own set of practical uses, depending on the field or region. Here’s a breakdown of their real-world applications:


  • Construction and carpentry: In the US and Canada, lumber dimensions, tool sizes, and building plans are given in inches for precision and familiarity. For instance, standard 2×4 lumber measures 1.5 inches by 3.5 inches.
  • DIY projects and crafting: Many household tools and materials like rulers, measuring tapes, screws, and fabrics are sized in inches, making them convenient for home improvement and creative endeavors.
  • Machinery and manufacturing: For specific parts and components, particularly in older equipment, imperial units like inches may be used for compatibility and standardization.
