A centimeter is a unit of measurement often used to measure the length of an object. According to the metric system, a centimeter (denoted as cm) is equal to one-hundredth of a meter, or in simpler words, there are 100 centimeters in a meter. But do you ever wonder how big is a centimetre actual size? Let’s find out examples of a centimeter in real life, and measure 1 cm on your finger with a centimetre example. Scroll through the article and you will get all your answers.

**1. What Size is Centimeter?**

The metric unit system has various units of measurement to measure length, area, mass, and capacity. For measuring lengths, we have kilometers, millimeters, and centimeters; for measuring weight, we have grams and kilograms; for volume, we have liters, milliliters, etc. Each unit’s size can be determined or it can be converted into another unit. Conversion basically means shifting the decimal point. One just needs to keep in mind the metric prefix, and the conversion can easily be done by multiplying or dividing the number by the value of the prefix. (See How many cm in a Metre?)

We can write 1 cm = 1/100 m or 0.01 m.

Or, 1 cm = **10 millimetres.**

**2. What is Centimetre Example?**

Are you trying to figure out a centimetre example? The most common centimeter example is a ruler. This measurement tool can measure small objects like notebooks, pencils, etc. Some other things that can be measured in centimeters are the waist size of pants, the length of a page, the sides of a triangle, measuring someone’s height, etc. (See What Instrument is Used to Measure Mass of an Object?)

**3. How Big is a Centimeter in Real Life?**

We know how big is a centimetre on a ruler and how big it looks on paper, although a centimeter in real life looks different when you look at it from a bigger perspective. **0.3937 inches make 1 cm.** This means that 1 centimeter is less than half as much as an inch. Almost two-and-a-half centimeter forms one inch. So, a centimeter might not look that small on a piece of paper, but in real life, it is very tiny. So, how big is a centimetre actual size? Let’s find out. (See How long is 7 inches compared to an object?)

**4. How Big is a Centimeter Actual Size? **

Determining how big is a centimetre actual size is not that difficult. A centimeter’s actual size is exactly** what you can see on the ruler that you use**. It is equal to 10mm. You already know how to convert centimeters to meters, millimeters, and inches, in addition to the centimetre example. That is the actual size of a centimeter. That is how big a centimeter in real life is. (See How Big is 4 Inches?)

**6. How Long is 1 cm on your Finger?**

Take a ruler and measure how big is 1 cm on your finger. Our fingers are divided into three joints. You will realize that when you vertically place the ruler beside your finger, not even one entire joint is covered in 1 cm. Although the width of an average pinky finger is 1 cm, **1 cm does not cover a good length of the finger. **(See How Deep is 10 Kilometers?)

**7. What is 1cm Thick?**

Are width and thickness the same? Or do length and thickness mean the same? Often getting confused? Let’s see, **length,** in simple words, means how long the object is.

**10. How do you Measure Centimeters with your Hand?**

Image by Elisa from Pixabay How big is a centimetre actual size? You already have the answer. In ancient times, when rulers did not exist, people still found ways to measure objects.

**1 inch**(2.5 cm) = length of the first joint of your index finger.**2 inches**(5 cm) = length of your thumb.**4 inches**(10 cm) = width of most people’s hands measured across their bottom knuckles (without the thumb).**6 inches**(15 cm) = range from the tip of the thumb to the tip of the index finger (when a hand is spread wide).**9 inches**(23 cm) = the distance between the tips of the thumb and the tips of the pinkies (when a hand is spread wide).**18 inches**(46 cm) = range from the elbow to the tip of the middle finger.
