- Uncertainty in Temperature Measurements
- Uncertainty in Volume Measurements from a Graduated Cylinder
- Exact Numbers

- Significant Figures are the digits in a measurement up to and including the estimated digit.
- Counting Significant Figures
- Moving the decimal point doesn't change the number of significant figures.
- A procedure for counting significant figures.
- When are zeros significant figures?
- Rounding to the Correct Number of Significant Figures
