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.
