c. Use one of your experimental conversion factors to determine a value in inches that is equivalent to 9.76 centimeters d. According to the universally accepted reference standard, 1 inch is equal to 2.54 cm. Use your experimentally determined conversion factor to convert 1 inch to its equivalent value in centimeters. Use your answer to evaluate the accuracy of your conversion factor. What does this tell you about the accuracy of your box measurements? 4 Paper clip A is known to have a mass of 1.1865 g. Paper clip B is known to have a mass of 1.1848 g. Suppose you are given one of these paper clips but not told which one.
