# How Big Is 4 Centimeters (10 Examples)

The size of 4 centimeters can be hard to visualize, so it’s important to understand how big or small this measurement is.

`Four centimeters (4cm) is an imperial unit of measurement. It is equivalent to 1.57 inches, 40 millimeters, or 0.04 meters in terms of length and size.`

In this article, we’ll discuss how big is 4 centimeters and provide some helpful examples for reference.

## 1. AAA Battery

AAA batteries are smaller and lighter than AA batteries, but they have a similar voltage (1.5 volts) and are generally used in devices that require less power. The size and shape of AAA batteries make them a convenient choice for many portable devices.

They are typically about 44.5mm long, which is very close to 4 centimeters.

## 2. A Golf Ball

Golf balls come in a variety of brands and styles, and each type is designed to perform differently based on factors such as speed, distance, and spin. Golf balls are an essential piece of equipment for golfers and are used on every hole of a golf course.

Golf ball is typically made of a rubber or synthetic material called Surlyn and has a diameter of about 1.68 inches (42.67mm). This means that a single golf ball will be slightly over 4 centimeters in diameter.

Business cards are typically made of cardstock and are about the size of a standard playing card, although the size and design can vary. They usually include the person’s name, job title, company name, and contact information, such as an email address, phone number, and physical address.

A standard business card is typically about the size of a standard playing card, which is 3.5 inches (88.9mm) wide. This means if we cut the width of a business card in half, it will be very approximately 4 centimeters.

## 3. Billiard Ball

The size of a billiard ball is standardized and is the same for all types of billiards games. According to the World Pool-Billiard Association (WPA), the official governing body for pocket billiards, the diameter of a standard billiard ball is 2.25 inches or 5.7 centimeters.

To get a length of 4 centimeters, you’ll need to subtract 1.7 centimeters from the total measurement. This adjustment will ensure that you have an accurate measurement.

A hockey puck is a hard, rubber disk that is used in the game of ice hockey. It is typically about 3 inches (76.2mm) in diameter and 1 inch (25.4mm) thick, and it weighs about 6 ounces (170 grams).

The hockey puck is used to score goals by hitting it into the opposing team’s net with a hockey stick. It is also used for face-offs, which are used to begin play or to restart play after a goal is scored or after a penalty is called.

If you were to cut a hockey puck in half, you would have two semicircular pieces of rubber, each about 38.2mm or 3.81 centimeters in diameter. This is just slightly shy of 4 centimeters.

## 5. A Common Matchstick

Matchsticks are commonly used to light candles, cigarettes, and campfires. They are also used in emergency situations as a source of light and heat.

The size of a matchstick is standardized and is typically about 4.80 centimeters long. Which is not exactly 4 centimeters but can give you a good idea about 4 centimeters.

Pennies are small, circular coins that are about the size of a U.S. quarter, which is 19.05 millimeters in diameter.

The width of two US pennies is 3.81 centimeters, just slightly shy of 4 centimeters. For an exact measurement of 4 centimeters, two nickels can be used instead: each nickel measures 21.21 millimeters in diameter, resulting in a total width of 4.242 centimeters when placed side by side.

## 7. A 12oz Soda Can

Soda cans are typically made of aluminum and are designed to hold approximately 12 fluid ounces (355 mL) of liquid.

The dimensions of a standard soda can are approximately 4.83 inches (12.27 cm) in height and 2.13 inches (5.41 cm) in diameter. Which is just 1.4 centimeters more than 4 centimeters.

## 8. Seven No. 2 Pencils

No. 2 pencils are the most common type of pencil and are used in a variety of settings, including schools, offices, and homes.

The dimensions of a No. 2 pencil will depend on the specific type and brand of pencil you are using. In general, No. 2 pencils are about 7.5 inches to 8 inches long and about 0.25 inches in diameter.

If you take 7 of the standard No. 2 pencils and lay them side by side, the total width will be approximately 4 centimeters. This is because a No. 2 pencil typically has a hexagonal shape with a thickness of 6 millimeters.

## 9. Two Almonds

Almonds are small, oval-shaped nuts with a hard, brown shell and a white, tender interior. They are a popular snack food and are often eaten raw, roasted, or as a component of other dishes, such as baked goods and salads.
