Solved Problems

Unit conversion is one of the topics that you need to master in order to do well in physics. Here, we have provided a few practice questions to help you better understand the concept.

Which is greater 45 kg or 4500 g?

Ans: 45 kg is greater than 4500 g as 45 kg = 45000 g

Calculate the height of the person 5’3″ tall in metres.

The conversion of height from feet to metres is a two-step process. First, convert the number of feet to metres, and then convert the number of inches to metres.
Converting feet to metres, we get
5 ft × 0.305 = 1.53 metres
Now, converting the inches to centimetres, we get
3 inches × 2.54 = 7.62 cm = 0.0762 metres
Adding these two together, we get
1.53 metres + 0.0762 metres = 1.6062 metres.
Therefore, the height in metres is 1.6062 metres.
