We recommend that measurements taken in inches are recorded in a shorthand notation system described in the Measuring Manual. A measurement of 1-1/8 inch is written as 1¹. A measurement of 1½ inches, 1 4/8 inches, is written as 1⁴. We welcome measurements in centimeters. Record these in standard decimal notation,for example, 1.5 cm. Since the majority of measurements we receive are in inches, it is a very good idea to let us know when you use centimeters.
