Question

The height of a person is 1.65m. Express it into cm and mm.

Answer 1

Hint- In order to solve this question, we will use the basic conversion factors to convert the given height from meters to centimeters and to do that we need to multiply the given number by the multiplying factor.

Complete step-by-step answer:
Given height of the person is 1.65m

As we know that

1m = 100cm

Therefore the height of the person in cm is

1.65 x 100 =165cm

Now to convert it into mm

We will multiply the given number by 1000

1m = 1000mm

Therefore

1.65m = 1.65 x 1000 = 1650mm

Hence, the height of the person in cm is 165cm and in mm is 1650mm.

Additional Information- Length is known as the degree of the measurement from one end to the other. Length is a scale quantity, and we find it in nearly every basic physical world phenomenon. Each Physics experiment needs a length to achieve desired results. The length depends on all other physical dimensions.

Take your height for example. How are you going to measure your height? How high are you? The length between the foot and the head is literally height. You may use a finger or a stone to determine the height. We need a unit to describe what length is so without a unit we can't equate dimensions or correlate 2 objects with their meanings.

Note- In order to solve these types of questions, you need to remember the conversion factors of length. Some of the conversion factors are. To convert meters into millimeters, we need to multiply the given number by 1000. i.e. 1m = 1000mm. Also, in order to convert a centimeter to mm, we need to multiply the given number by 10 .i.e. 1cm = 10mm. Similarly other conversion factors can be remembered.
