Purpose: The purpose of this lab is to be able to properly use all units of the metric system, and be able to convert the metric units into those that are similar. In order to identify which metric system is being used, it is determined by the measuring device in which is supplied: Thermometers read degrees celsius, graduated cylinders read volume; milliliters, and two forms of weight devices similar to scales called Analytical Balance and Triple Beam Balance in which measure mass. When reading, measuring, or balancing, it is key to make sure all numbers are precise, measuring all liquids at eye level, and using the correct forms of significant figures. Significant figures are a vital part in any kind of data recorded because without it there…show more content… First, measurement in length in centimeters is being used to measure the width of the laboratory manual. Unfortunately, it's not going to be that easy because centimeters isn’t the length that is needed for this report. In order to complete this portion of the lab correctly, centimeters must be converted to inches using this equation (found in the appendix of the lab manual): (X) cM= 1 in/2.54 cM. In this equation, x represents the width of the laboratory manual measured following the amount of centimeters that are found in one inch. Second, measurement of volume will be recorded using a graduated cylinder. Prior to beginning lab, two graduated cylinders must be be filled with different amounts of tap water in which should be prepared by the instructor. Before any kind of recording of how much water is in all the cylinders, it is most important to see what kind of unit is being used. For this instance, milliliters are being used to measure volume. Following the figuring out that the unit is milliliters, it is time to read how much water is precisely in the instrument. Depending on the area and height of which the cylinder is placed, it is important to always read it at eye
