Centimeters. Notes on Recording Lab Data: Estimate the difference between two divisions. The push pin to the right measures 2.25 more than the divisions on the scale. The last decimal place will be based on the measurement scale. In each case, record one decimal place. For analog measurements, the number of decimal places you report will vary. For digital measurements, record all digits shown on the display, i.e. 2.569 grams. cm^3 C CH.
