Activity 3.1 B Linear Measurement
Procedure
In this activity you will practice taking linear using SI measurements with a metric ruler and correctly recording the measurements to reflect the precision of the measurement.
Record the length of the rectangles shown in the following figure using SI units and the correct number of significant figures. Include the units in your answers.
Conclusion
1. Explain the meaning of significant digits (or significant figures) in measurement.
2. Why is the metric system used instead of the US customary system, and vice versa, in various parts of the world?
