SECTION VII – APPENDIX
1. General
(a)
Conversion tables in this section are provided as a source of quick reference information.
(b)
Equipment, consumables, and specifications called out in the text are listed on individual tables.
2. Conversion Tables and Charts (Measurement and Drill Bit Sizes)
(a)
Inch fractions, decimal, millimeter equivalent are listed in Table 701.
(b)
Drill size decimal equivalent is listed in Table 702.
3. Temperature Conversion
Table 703 (Fahrenheit to Centigrade/Celsius Conversion) and Table 704 (Centigrade/Celsius to Fahrenheit Conversion) are provided to assist in obtaining accurate conversions of Fahrenheit to Centigrade/Celsius and vise-versa.
NOTE: When using the conversion tables, care should be exercised to differentiate between direct conversion of Fahrenheit to Centigrade/Celsius (95F equals 35C) or Centigrade/Celsius to Fahrenheit (100C equal 212F).
To convert temperature differences, use either of following two methods:
.
Method A—Convert both temperatures, using the appropriate table, and subtract the lower temperature from the higher temperature.
.
Method B—Use the interpolation factor to obtain the temperature difference.
Fahrenheit 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0
Centigrade/Celsius .06 .11 .17 .22 .28 .33 .39 .44 .50 0.56
Centigrade/Celsius 0.1 0.2 0.3 0.4 0.5 0.6 0.7 0.8 0.9 1.0
Fahrenheit 0.18 1.36 0.54 0.72 0.90 1.08 1.26 1.44 1.62 1.80
A. Examples 1: Fahrenheit to Centigrade/Celsius Conversion
Convert a 100F (200F - 100F) temperature differential, or the difference between 200F and 100F, to Centigrade/Celsius.
NOTE: An inaccuracy of 0.45 degree is due to rounding of 0.5555 degree to 0.56 degree. This is not significant at low temperature differentials, but may become significant at higher differentials (such as 1000 degrees). Therefore, Method A should be used when converting large temperature differentials.

. Method A - Using the conversion table (Table 703)
200F = 93.33C
100F = 37.78C
55.55C difference
. Method B - Using the interpolation factor
.56C
100C ×= 56C difference
1F
B. Examples 2: Centigrade/Celsius Conversion to Fahrenheit
Convert 100C (200C - 100C) temperature differential, or the difference between 200C and 100C to Fahrenheit:
. Method A - Using the conversion table (Table 704)
200C = 392F
100C = 212F
180F difference
