# How Big is 5 Millimeters (mm)? 12 Common Examples

It’s important to have a clear understanding of what each unit represents. One commonly used unit is the millimeter (mm), which is a standard unit of length in the metric system. But how big is 5 millimeters (mm)?

5 mm is equivalent to 0.5 centimeters, 0.1969 inches, or 0.0164 feet.

In this post, I will explore the size of 5 millimeters (mm) and provide examples of objects that are 5 mm thin.

## The Size of 5 Millimeters (mm)

So, how big is 5 millimeters (mm)? To put it into perspective, 5 millimeters is approximately the thickness of two dimes stacked together. It’s also equivalent to 0.5 centimeters, 0.1969 inches, or 0.0164 feet.

When it comes to everyday objects, 5 millimeters is a relatively small size. For example, the average thickness of human hair is around 0.1 millimeters, which means that 5 millimeters is 50 times thicker than human hair.

## Common Objects That Are 5 mm Thick

### 50 Sheets of Paper

A standard sheet of paper is typically 0.1 millimeters thick. Therefore, 50 sheets of paper stacked together would have a total thickness of approximately 5 millimeters.

It’s important to note that the exact thickness can vary depending on the type of paper, weight, and size of the sheets.

### Wedding Ring

A wedding ring is a type of ring that is typically worn by a person to symbolize their marriage. It is usually made of precious metals such as gold, silver, or platinum and may be decorated with diamonds or other gemstones.

### 4 Cdâ€™s

A CD, short for compact disc, is a digital optical disc used to store and play audio, video, and other types of data. A standard CD has a diameter of 120 millimeters and a thickness of 1.2 millimeters. So, the combined thickness of four CDs would be around 5 millimeters.

### Pencil Top Eraser

A pencil top eraser is a small eraser that is designed to be placed on the end of a pencil. It is used to remove mistakes and errors made when writing or drawing with a pencil.

Pencil top erasers come in various shapes and sizes, but the typical thickness of a standard pencil top eraser is around 5-6 millimeters.

### 2 USB C Ports

USB-C ports are a type of connector that is commonly used for data transfer and charging in electronic devices such as laptops, smartphones, and tablets.

The thickness of a single USB-C port can vary depending on the device it is on, but it typically ranges from 1.83 to 2.87 millimeters.

So, the combined thickness of two USB-C ports would be approximately 5 millimeters.

### Small Hex Nut

A hex nut is a type of fastener that has six sides and is used to secure bolts, screws, or other threaded parts. Small hex nuts are usually made of metal and are commonly used in machinery, electronics, and other mechanical applications.
