In addition to simple conversions, it shows equivalent lengths between meters, millimeters and feet so you can get a complete picture of your measurement from various points of view. Ideal for students, professionals, do-it-yourselfers, and anyone who works with measurements from more than one system.

Full of real world examples like comparing the size of your house to a football field, our unit conversion tool can be used step-by-step to show students how to convert units with Flippity's minimal design that's easy on the eyes. No more manual math or remembering complicated conversion tables receive accurate data instantly.

How to Convert Centimeters to Inches

Converting centimeters to inches is a straightforward process that involves a simple multiplication. The conversion factor between these two units is well-established and consistent.

Step-by-Step Conversion Process:

  1. Identify the number of centimeters you want to convert
  2. Multiply the centimeter value by 0.393701 (the conversion factor)
  3. The result is the equivalent measurement in inches
Formula: Inches = Centimeters × 0.393701
Example 1: 10 cm × 0.393701 = 3.93701 inches
Example 2: 25 cm × 0.393701 = 9.84252 inches
Example 3: 100 cm × 0.393701 = 39.3701 inches

Or you could divide centimeters by 2.54 to obtain inches because 1 inch is equivalent to 2.54 centimeters. Both of these approaches give same result. For example, if you divide 50 centimeters by 2.54, you get the value of 19.685 inches that we would expect from multiplying by.393701.

if you’re working with big numbers, feel free to use a calculator or our conversion tool as needed. For rough mental conversion, remember that about 2.5 centimeters equals 1 inch, so with very little difference for estimates you can develop a habit of dividing the number of centimeters by 2.5 to find an approximation in inches.

How Many Inches Are in a Centimeter?

There are 0.393701 inches in a centimeter exactly. This particular conversion factor comes from the international definition of an inch being exactly 2.54 centimeters. If you inverse this relationship (1 ÷ 2.54), that’s 0.393701 inches per centimeter.

This means that the centimeter is smaller than the inch; in fact, to make one inch there are more or less 2.54 centimeters. Just to help make sense of this, consider a centimeter is about two-fifths—or 40%—of an inch. This relationship is fixed and does not vary with measurement sizes.

1 centimeter = 0.393701 inches
1 centimeter = 0.0328084 feet
1 centimeter = 0.01 meters
1 centimeter = 10 millimeters

It can also come in handy if you ever have to calculate conversions off the top of your head. In easy-to-remember terms, if something is 5 centimeters, you can approximate that to be about 2 inches (5 × 0.4 = 2). For the precise calculations, use the exact conversion factor of 0.393701 or our converter below.

How to Convert Centimeters to Fractional Inches

Changing centimeters to vertical inches is useful in construction, woodworking and engineering where measurements are frequently in these fractions like 1/2, 1/4, 1/8 or 1/16 of an inch. This technique gives results compatible with standard rulers and measuring devices.

Conversion Process for Fractional Inches:

  1. Convert centimeters to decimal inches using the standard formula (cm × 0.393701)
  2. Identify the whole number of inches (the integer part)
  3. Take the decimal portion and convert it to the nearest common fraction
  4. Common fractional increments include: 1/16, 1/8, 1/4, 1/2, 3/4, etc.
Example 1: 2.54 cm = 1.0 inch = 1 inch exactly
Example 2: 3.175 cm = 1.25 inches = 1 1/4 inches
Example 3: 5.08 cm = 2.0 inches = 2 inches exactly
Example 4: 6.35 cm = 2.5 inches = 2 1/2 inches
Example 5: 10.16 cm = 4.0 inches = 4 inches exactly

Common Fractional Inch Equivalents:

1/16 inch = 0.15875 cm
1/8 inch = 0.3175 cm
1/4 inch = 0.635 cm
1/2 inch = 1.27 cm
3/4 inch = 1.905 cm
1 inch = 2.54 cm

When even higher accuracy is needed, round to the nearest 1/16th or 1/32nd of an inch—whatever your project guidelines are. For typical applications, rounding to the nearest 1/8" or 1/16" is adequate and can be made using standard measuring devices.

What Is a Centimeter?

A centimeter (cm) is a metric system base length unit. It is one-hundredth (1/100) of a meter and used to measure things that are neither too big nor too small.

The centimeter is part of the International System of Units (SI), which provides standardized measurements for scientific and everyday use. The word "centimeter" comes from the Latin "centum" meaning "hundred" and "meter," reflecting its relationship to the base unit of length.

Key Characteristics of Centimeters:

  • 1 centimeter = 0.01 meters (1/100 of a meter)
  • 1 centimeter = 10 millimeters
  • 1 centimeter = 0.393701 inches
  • Commonly used for measuring height, clothing sizes, and everyday objects
  • Part of the metric system used in most countries worldwide

Centimeters are most commonly employed in measuring objects that are not long enough to study meters, but large enough that the use of millimeters result obtuse ratios. Typical uses include the dimensions of a person (e.g. 175 cm tall), the size of a book (14 cm wide), or other object.

For scientific use, centimeters are a good compromise between precision and convenience; readily converted to millimeters if need be or translated into feet for non-metric imperial measure. They’re big enough to be easily seen and measured with regular tools, but small enough to maintain useful detail for most common measurements. Decameters, decimeters and centimeters The decimal nature of the metric system makes it easy to convert from one unit that is a power of ten to another such unit.

What Is an Inch?

An inch (abbreviated as in or ″) is a unit of length in the (British) imperial and United States customary systems of measurement. It is also among the most ubiquitous units of measurement in use for lengths in the United States, the United Kingdom and Canada.

An inch was originally defined as the width of a man's thumb, be it however, international standardization has made this definition obsolete. Since 1959, the inch has been officially defined to be exactly 25.4 millimeters which is making it easier to design products since available metric sizes are in even numbers.

Key Characteristics of Inches:

  • 1 inch = 2.54 centimeters (exact conversion)
  • 1 inch = 1/12 of a foot
  • 1 inch = 1/36 of a yard
  • 12 inches = 1 foot
  • 36 inches = 1 yard

Inches are frequently separated into fractional sections dependent on how they will be used and the most common ones that people use everyday are: 1/2, 1/4, 1/8, and 1/16. This fractional system is really entrenched in construction and manufacturing and engineering in imperial system based countries.

Common Uses of Inches:
• Screen sizes for TVs, monitors, and smartphones
• Paper sizes (e.g., 8.5" × 11" letter size)
• Construction measurements and building materials
• Tire sizes and wheel diameters
• Height measurements in everyday conversation

The inch remains a crucial unit of measure in many fields, especially in the United States, where it’s used for everything from architectural blueprints to product specifications. Knowledge of/inches and their relation to the metrical system--An indispensable requirement for international traffic.
