Millimeters

**What is a centimetre?**

A centimetre is a unit of length that is equal to one-hundredth of a metre in the International System of Standards (SI). It is denoted as ‘cm’ in short.

Common Usage:

- Used to measure the length of textbooks.
- Used to measure the length of pens.
- Used to measure the length of bottles.

**What is a millimetre?**

In the International System of Units (SI), a millimetre is a unit of length equal to one-thousandth of a metre. It is denoted as ‘mm’ in short.

Say a few examples of millimetres would be:

- The size of the dial of a wristwatch
- The size of a diamond
- The size of a coin

**How do you convert a centimetre to a millimetre?**

To convert the centimetre to the millimetre, multiply the required centimetre by 10 as,

1 cm = 10 mm

Formula,

Y cm = Y × 10 mm

**Examples of centimetre to millimetre conversions**

**Problem 1:** Convert 100 centimetres to millimetres.**Solution**:

Step 1: The required centimetres is 100.

Step 2: The formula to convert centimetres to millimetres is,

Y cm = Y × 10 mm

Step 3: Substitute the required values in the above formula. Hence,

100 cm = 100 × 10 mm

= 1000 mm

Therefore, 100 centimetres is 1000 millimetres.

**Problem 2:** Convert 250 centimetres to millimetres.**Solution**:

Step 1: The required Centimetre is 250.

Step 2: Substitute the values in the formula & convert the required centimetres to millimetres, as mentioned in the previous example. Hence,

250 cm = 10 × 250

= 2500 mm

Therefore, 250 centimetre is 2500 millimetre.

**Problem 3**: Convert 600 centimetres to millimetres.**Solution**:

Step 1: The required Centimetre is 600.

Step 2: Substitute the values in the formula & convert the required centimetres to millimetres. Hence,

600 cm = 10 × 600 mm

= 6000 mm

Therefore, 600 centimetres is 6000 millimetres.

**Problem 4**: Convert 4 centimetres to millimetres.**Solution**:

Step 1: The required Centimetre is 4.

Step 2: Substitute the values in the formula & convert the required centimetres to millimetres. Hence,

4 cm = 10 × 4 mm

= 40 mm

Therefore, 4 centimetre is 400 millimetre.

**Problem 5**: Convert 10 centimetres to millimetres.**Solution**:

Step 1: The required Centimetre is 10.

Step 2: Substitute the values in the formula & convert the required centimetres to millimetres. Hence,

10 cm = 10 × 10

= 100 mm

Therefore, 10 centimetre is 100 millimetre.
