 # Unit Conversion

There are a few things as the following that we measure in our day-to-day activities, and they are:
• Speed
• Temperature
• Area
• Volume
• Mass

To measure these quantities, units of measurements are required. There are times when the units used for the measurement do not match the measurement preference and convenience as well as the standards prescribed for certain processes and applications. Converting such units to an extent that it can be understood directly and applied properly is important. To better understand the statement, let us consider the example of a person who is only familiar with the metric system. The person cannot easily figure out the height of a tree measuring 25 feet. Converting 25 feet to metres will help the person better understand the height of the tree. Let us learn unit conversions with the help of a unit conversion table. In this article, we have provided different units of conversion used for the measurement of different parameters.

## 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.
