5 cm to inches ruler

This is an online length converter that converts millimeters (mm) to inches, centimeters (cm) to inches, inches to centimeters, inches to mm, includes a ruler to show the respective units and helps you understand my question ''5 cm to inches ruler''

with the most intuitive image.

How to Read Inches and Centimeters on a Ruler

• Fill in the blanks to convert MM to fractional inch. MM, for example, 16 mm 5/8 inch

• Fill in the blanks to convert CM to fractional inch. CM, for example, 8 cm 3 1/8", use a smaller scale (1/32"), 8 cm 3 5/32"

• Use 1/8" graduations for 10cm = 4"; 1/16" graduations for 10cm = 3 15/16"

• Fill in the fraction to convert fractional inch to mm or cm. 2 1/2" = 2.5" is a fractional inch.

• Fill in the blank with decimal inch to convert it to fractional inch. Decimal inch, for example, 3.25" = 3 1/4"

Changing the size of this virtual ruler to the actual size

My laptop computer's diagonal screen measures 15.6" (inches) and has a resolution of 1366x768 pixels. I googled the PPI reference and found 100 PPI on my screen. After measuring the size of the virtual ruler with a real ruler, I discovered that the markings are not very accurate at 30cm, so I set the default pixels per inch (PPI) for myself to 100.7.

If you want this online ruler in actual size, you can adjust the pixels per inch (PPI) to suit your device.

How to Read an Inch Ruler

Let's begin by learning how to read a ruler in inches. If you're an American, you're probably more familiar with this measurement than centimeters, which are sometimes included on your standard 12-inch, or 1-foot, ruler (we'll go over how to read a ruler in cm in the next section).

An inch ruler is shown below:

You should be able to tell right away that this ruler is in inches because it is divided into 12 evenly spaced areas (labeled 1-12), and we know there are 12 inches in a foot (ignore the cm below).

Take note of the lines that run between each inch, some longer and some shorter than others. Each of these tiny lines is a fraction of an inch long. There are five different line lengths in total.

Each inch is divided into 16 lines, so the space between each line is 1/16 inch long—the smallest length a ruler can measure. (It should be noted that some rulers only go down to 1/8 inch lines, while others go down to 1/32 inch lines.

The inch is the longest line on a ruler and is the largest unit. Each 1-inch line on the ruler is labeled with a number indicating the inch (as the image above shows).

When you measure the length of a sheet of computer paper, it will come up to the 11-inch mark on your ruler, indicating that it is exactly 11 inches long.

The 1/2 inch is the second-largest unit on a ruler, represented by the second-longest line. These aren't usually labeled, but they may be on some rulers (in which case you'd see numbers like 1 1/2 in, 2 1/2 in, and so on).

On a ruler, the 1/2-inch line is located halfway between each inch. 7 1/2 (or 7.5) inches would be the midpoint between 7 and 8 inches, for example.

How to Read a Centimeter Ruler

Now that we've covered how to read a ruler in inches, let's look at how to read a ruler in centimeters.

This is especially important to understand if you're studying science (remember, science uses the metric system, not the imperial system). Knowing how to read a ruler in cm is also useful for people who prefer not to work with fractions (which is required with inches) and would rather work with other units (in this case, millimeters).

Now that we've covered how to read a ruler in inches, let's look at how to read a ruler in centimeters.

This is especially important to understand if you're studying science (remember, science uses the metric system, not the imperial system). Knowing how to read a ruler in cm is also useful for people who prefer not to work with fractions (which is required with inches) and would rather work with other units (in this case, millimeters).

The standard metric ruler measures 30 cm in length. Each centimeter is labeled with a number to indicate the measurement to which it refers. On the other side of your metric ruler, you might see inches. In this case, follow the instructions above to learn how to read an inch ruler.

Also, keep in mind that 30 cm does not directly equal 12 inches, despite the fact that they are frequently used on the same ruler!

Here's an example of a standard metric ruler:

This is a metric ruler because it is divided into 30 evenly spaced sections and has "cm" written on it (ignore the inches below).

A metric ruler, like an inch ruler, has a plethora of lines, some longer than others. Each line represents one millimeter, which is one-tenth of a centimeter (0.1 cm) (so 10 mm make up 1 cm).

From one centimeter to the next, there will always be ten lines. On a metric ruler, there are three different lengths of lines.

The longest line represents the ruler's largest unit: 1 cm. On the ruler, each centimeter is labeled (1-30).

Assume you're measuring the width of your fingernail with a ruler. The ruler stops at 1 cm, so your nail is exactly 1 cm wide.

The 1/2 (0.5) centimeter line on a metric ruler comes halfway between every centimeter (in other words, it's the fifth line after every whole centimeter):

So if you counted five lines from 9 cm, you'd get 9.5 cm (or 95 mm).

Assume you're measuring the width of your smartphone and you reach the fifth line after 4 cm on your ruler. This means the phone is 4.5 cm (45 mm) wide.

A metric ruler can measure 1 mm (0.1 cm) as the smallest unit. These are the smallest lines on the ruler, those that fall between a whole centimeter and a half centimeter:
