TM 9-243READING THE SCALE OF A RULE OR TAPE - ContinuedNow turn the rule and look at the edge with a 16 markedon it.There are now 16 equal divisions between each inch.Since 2/16 reduces to 1/8, divide each 1/8 into twoequal parts producing 1/16, 3/16, 5/16, 7/16, 9/16,11/16, 13/16, and 15/16.Common tapes and rules usually are not graduatedsmaller than sixteenths. However, precisionmeasurements require smaller graduations.Look at the back of the machinist's rule. Find the edgemarked 32 and once again look between the numbers"2" and "3."To read this rule, remember:1.Sixteen divisions (16/32) are equal to 1/2 inch.2.Eight divisions (8/32) are equal to 1/4 inch.3.Four divisions (4/32) are equal to 1/8 inch.4.Two divisions (2/32) are equal to 1/16 inch.To read 2-5/8 inches on the scale, first find the two inchmark, then determine the number of 32nds in 5/8.To determine the number of 32nds in 5/8, rememberfour divisions or 4/32 are equal to 1/8 inch. If 1/8 isequalto 4/32, then 5/8 is equal to 20/32 as shown:If 1/8 = 4/32, then 5/8 = 20/32(4 x 5 = 20)1.Find the 20/32 reading on the scale as shownabove.2.Write the new fraction 2-20/32 inches.Finally, look at the edge marked 64. Each inch is nowdivided into 64 equal parts.To read this rule, remember:1.Thirty-two divisions (32/64) are equal to 1/2inch.2.Sixteen divisions (16/64) are equal to 1/4 inch.3.Eight divisions (8/64) are equal to 1/8 inch.4.Four divisions (4/64) are equal to 1/16 inch.5.Two divisions (2/64) are equal to 1/32 inch.To read 2-3/4 inches on this scale, first find the two inchmark. Next, determine the number of 64ths in 3/4.3-2
