## 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.
