science physics# Do sig figs apply to conversions?

Last Updated: 18th February, 2020

**Use significant figures**as much as you can in intermediate

**conversion**factors,and then round off the final answer to two

**significant figures**,using more

**significant figures**in intermediate

**conversion**factors will lead to a accurate answer.

Also, how many significant figures can you justify in your conversion factor?

two significant figures

how many significant figures does 10.0 have? two

Beside this, do sig figs matter in dimensional analysis?

Because there is no uncertainty, exact numbers have an infinite number of **significant figures**, and they **do** not **affect** the **significant figures** of the final answer when they are used in a calculation. would determine the **significant figures** of the conversion factor (3 **sig**. **figs**.).

How do exact numbers affect significant figures?

00250 has two **significant figures**. 005.00 x 10¯4 has three. **Exact numbers**, such as the number of people in a room, have an infinite number of **significant figures**. Therefore, if a number is **exact**, it **DOES** NOT **affect** the accuracy of a calculation nor the precision of the expression.
