In this Physics tutorial, you will learn:

- What are significant figures?
- How to find the number of significant figures in a given numerical value?
- How to round up a number to the required number of significant figures?
- Why are significant figures so important in measurements?

The flying distance from London to Birmingham is about 101 miles (or 163 km). Can we say "101.000 miles or 163.000 km" to be more precise? Why?

The weight of an African bush elephant is about 6000 kg. Can we say, "Elephant's weight is 6000.000 kg" to be more precise? Why?

The dimensions of a door are 194 cm × 87cm. Can we round up the result and say to the carpenter to produce a door with dimensions 2m × 1m? Why?
