The measurement of 2 millimeters is very small and precise. This is a unit of measurement in the metric system that is required for measuring the diameter, dimension, or height of tiny objects.

## How Big is 2 Millimeters?

As we all know that a unit of measurement can be expressed in several other units depending on their relation, a millimeter can also be expressed in centimeters, meters, etc. Here are some of the common relationships that millimeter has with other units of the metric system.

How Big is 2 Millimetres?** **2 millimetre = 0.2 centimeters (cm) = 0.078 inches = 0.002 meters = 2000 micrometres

## Common Objects Compared to 2 millimeters

Now let us have a look at some of the common objects that can be observed to understand the measurement of 2 mm.

### 1) Tip of the Crayon

Yes! Indeed we are talking about the colorful wax sticks that are used by children in schools and at home to express their creativity on paper. The length of the unused crayon pencil is 3.5 inches but here it is certainly not the length that is under discussion. If you have observed with the tip of the crayon then you will know how slim and small it is! Well, that is exactly what we are trying to show you. The tip of the crayon is around 2 mm and a good example that we can pick up to show the measurement of 2 mm in real life.

### 2) Thickness of 20 sheets of paper

We have papers in our notebooks, dairies, or as loose sheets for writing documents and for use in schools and offices. However, the dairy and notepads in school and offices are thick, aren’t they? Well, those are made of several sheets of paper but if you take up just a single sheet of paper then we are talking about the thickness of a single sheet. The thickness of a singular sheet is about 0.05 to 0.10 mm. Hence if you have 20 such sheets stacked upon each other then you will get the measurement of 2 mm.

### 3) Thickness of Nickel Coins

Nickel coins used in the USA have a value of five cents and it is manufactured with a constant thickness of 1.95mm. Thus if you observe the thickness of a single nickel coin then you will note the height of 2 mm. Here is another example to describe the height of 2 millimeters with common things around us.

### 4) Two Dimes width

Dimes are the currency of money in Canada and these coins are useful for estimating the height of 2 millimeters. These dimes measure up to 10 cents in value and are easily available for us to observe. Each of the dimes shares a width of 1.22 mm. Hence if you can stack up two such identical dimes on top of one another then you will get a height that is very close to 2 millimeters. Hence we can easily observe the measurement of 2mm with common things like coins around us.

### 5) Double the diameter of a Sharpened Pencil

The students and kids often require a pencil to complete their homework and it is an essential part of stationery. The pencils after prolonged use need to be sharpened from time to time to write smoothly on paper. The diameter of the sharpened tip of the pencil is one millimeter and we can say that 2 mm is double the size of the sharpened tip of the pencil. Hence here we have another useful and commonly found example to describe the exact size of two millimeters. Here we see that the given size of the pencil tip is 1 millimeter thus half of the measurement of 2 mm.

### 6) Half of the pencil-top eraser

Here is another example that we can derive to discuss the dimension of 2 millimeters. You must have seen pencils with a small eraser at the end. Yes, we are talking about the diameter of that small eraser on the end of the pencil. These erasers are 5 millimeters in diameter and hence we can see that 2 millimeters are almost half the size of the eraser at the end of the eraser and thus easy for us to visualize.

### 7) 1/10th the size of a Peanut

We all find peanuts healthy and great to munch upon as a snacking option. These peanuts are also used in cooking and are a favorite choice among the little ones. The size of the peanut is 20 millimeters which measures 2 millimeters easy to explain with a comparison drawn between both. We see that the measurement of 2 mm is exactly 1/10th the size of the peanut which is approximately about 20 mm. Hence here is another example that we can pick up for comparison and explanation.

## FAQs

### How do we measure mm with the help of a scale?

If you take the normal thirty-centimeter ruler or 15-centimeter ruler/scale, students usually use then you will see that the measurement of each small marking on the ruler is equivalent to 1 mm. Then the slightly longer marking is equal to 5 mm and 10 millimeters is equivalent to 1 centimeter. Hence we see that counting the markings is the only way to measure a unit in millimeters on the scale. Similarly, you can measure 10,20,30 millimeters which will coincide with 1,2,3 centimeters.

### What is the size of a pea when measured in scales of millimeters?

You have seen a pea pod right? There are five to six peas in a pea pod. Now let us have a look at the size of a pea and measure its diameter. The size of a pea is around 7 to 10 mm which is equal to the size of around 1 centimeter. Hence we see that the measurement of 10 mm which is equivalent to 1 centimeter is the size of a single pea in the peapod. 1 millimeter is 1/10th of 10 mm.
