TM 9-2320-361-34 APPENDIX E (Contd) E-5. CONVERSION FORMULA Corrected dial or scale readings are determined by the use of the following formula: Corrected reading = Example: Required Length of torque wrench + Length of adapter torque value + Length of torque wrench NOW The length of the torque wrench is measured from the center of the handle to the center of the drive. The length of the adapter is measured from the center of the drive to the center of the wrench. In this example, the torque wrench measures 22 in. (55.9 cm) and the adapter is 3 in. (7.6 cm). The required torque is 19 lb-fl (25.8 N.m) Corrected reading Corrected reading Corrected reading Corrected reading 19 Ib-ft (25.8 N.m) + 22 in. (55. 9 cm) + 3 in. (7.6 cm) = 22 in. (55.9 cm) 19 lb-ft (25.8 N.m) + 25 (63. 5 m) = 22in. (55.9 cm) 19 lb-ft (25.8 N.m) + 1.14 = 17 lb-ft (23.1 N.m) = E-4
