Conversion tables direct equivalents

Even so, you may occasionally come across an older formula given in U.S. customary units. Should you wish to convert from one to the other you will want to use the compound conversion chart found under Conversion Tables at the back of the book. This is because the figures are not directly interchangeable between U.S. customary and metric, because 1.0 liter of water does not exactly equal 32.0 oz. Therefore, they must be specially compounded to be equivalent. 

For direct conversions between metric and U.S. customary units, use the following tables. However, if you intend to convert an entire U.S. customary formula using 32 ounces of liquid to a metric formula using 1 liter, or vice versa, use the compound equivalents following these tables. To convert an individual measure, use the direct equivalents. 

Table 5.7 lists the nucleophilic constants for a number of species according to this definition. It is apparent from Table 5.7 that nucleophilicity toward methyl iodide does not correlate directly with basicity. Azide ion, phenoxide ion, and bromide are all equivalent in nucleophilicity but differ greatly in basicity. Conversely, azide ion and acetate ion are... 

See Table 1 for direct conversion of ppm NaCl equivalent to pptb. 

In practice, the instruments are properly calibrated to read directly Sv (or rem), or Gy (or rad). For some neutron detection instruments, the neutron flux is recorded. Then the dose equivalent is obtained after multiplying the flux by the conversion factor given in Table 16.4. Since different detectors do not have the same efficiency or sensitivity for all types of radiation and for all energies, there is no single instrument that can be used for all particles (a, y, n) and all energies. 

As shown in Table III, a low heating rate (T6 min. to 3 0°C), implying a residence time of 30 minutes between 250 and 3 0°C, leads to a conversion of 20.2 7o of wood into char, when with an equivalent residence time at 3 0°C after a rapid hydropyrolysis, the production of char is only 12,k %. Moreover, a residence time of 30 minutes at 300°C without iron, leads to the formation of a black powder (it.2 %) that can be considered as an irreversible condensation product. Consequently, it appears that the residence time in the 250-300°C range is critical for the direction of the conversion of wood either into liquid compounds or on the contrary towards char, but then the liquids obtained at higher temperature are less sensible to recondensation into solids.
