NOTE.—The numbers in bold face type refer to the temperature either in degrees Centigrade or Fahrenheit which it is desired to convert into the other scale. If converting from Fahrenheit degrees to Centigrade degrees the equivalent temperature will be found in the left column, while if converting from degrees Centigrade to degrees Fahrenheit, the answer will be found in the column on the right. These tables are a revision of those by Sauveur & Boylston, metallurgical engineers, Cambridge, Mass. Copyright, 1920.

EXAMPLE.—If the weight of a carbon steel disc 7 in. diameter, 1-5/8 in. thick is desired, turn to page 233, where the per foot weight of 7 in. round is given as 131.6 lb. Multiply this by the decimal equivalent of 1-5/8 in., or 0.135, as shown in the above table, and the product will be the net weight of the disc.

131.61 lb. = the weight of 1 ft. of 7 in. round.

0.135 = the per foot decimal equivalent of 1-5/8 in:

65805

39483

13161

17.76735lb. = weight of disc 7 in. diam. 1-5/8 in. thick without any allowance for finishing.
