Centimeters and inches: they’re both units of length, but they come from different measurement systems. So, how do you convert between them? This article explains how to convert 10.4 cm to inches.
The good news is, it’s pretty simple: 10.4 cm is about 4.09 inches.
What are centimeters and inches?
Let’s define these units of measurement to make sure we’re all on the same page.
Centimeters (cm)
A centimeter is a unit of length in the metric system. One centimeter is 1/100th of a meter, and it’s part of the International System of Units (SI).
Inches (in)
An inch is a unit of length in both the imperial and U.S. customary measurement systems. One inch is 1/12th of a foot. These days, an inch is defined in relation to the metric system: one inch is exactly 25.4 millimeters.
How to convert centimeters to inches
The formula for converting centimeters to inches is pretty simple:
Inches = Centimeters / 2.54
That “2.54” is important because 1 inch equals 2.54 centimeters.
So, to convert 10.4 cm to inches, you just divide 10.4 by 2.54:
10.4 cm / 2.54 = 4.094488189 inches
For most uses, you can round that to 4.09 inches. So, 10.4 cm is about 4.09 inches.
Understanding Decimal and Fractional Inch Conversions
When we convert 10.4 cm to inches, we get 4.09 inches. This is expressed in decimal form, which is how inches are often written when precision is needed.
But sometimes, inches are expressed as fractions (1/2, 1/4, 1/8, 1/16, 1/32, 1/64, and so on). To convert our decimal inches to fractional inches, we need to find the fraction that’s closest to the decimal part of our inch value (0.09).
In this case, 0.09 inches is pretty close to 1/11 of an inch or a little closer to 1/16 of an inch. Depending on what you’re measuring, you may or may not need to be this precise.
