What is Understanding Percentage Error and Significant Digits about?

When dealing with percentage errors of measurements, the percentage error of multiplying or dividing measurements is equal to the sum of the individual percentage errors if the uncertainties are small. Significant digits indicate the accuracy of a measurement, with measurements rounded to the precision of the measuring tool. For a measurement of 6.125 cm with a ruler precise to 0.1 cm, the number should be rounded to 6.1 cm, which has 2 significant digits.
