Table A-4. Conversion Factors for Second Order Rate Constants (9)... 

The SI system also specifies standard multiples to be used to conserve space when numerical values are expressed. They are summarized in Table 1-3. Standard symbols for quantities normally encountered in heat transfer are summarized in Table 1-4. Conversion factors are given in Appendix A. 

A measured quantity consists of a number and a unit. Conversion factors are used to express a quantity in different units and are constructed as a ratio of equivalent quantities. The probiem-soiving approach used in this text usually has four parts (1) devise a plan for the solution, (2) put the plan into effect in the calculations, (3) check to see if the ansvwer makes sense, and (4) practice with similar problems. 

Note you do not need to use the molar mass of Ni(CO)4. Because it is a gas at standard temperamre and pressure conditions, the molar volume is a useful conversion factor to change volume to moles. ...

As another example of the use of a unit conversion factor, calculate the number of liters of gasoline required to fill a 12-gallon fuel tank, given that there are 4 gallons in a quart and that a volume of 1 liter is equal to that of 1.057 quarts. This problem can be worked by first converting gallons to quarts, then quarts to liters. The two unit conversion factors required are the following... 

A representative list of conversion factors from non-SI to SI units is presented herewith. Factors are given to four significant figures. Exact relationships are followed by a dagger. A more complete Hst is given in the latest editions of ASTM E380 (4) and ANSI Z210.1 (6). 

Table 1-7 provides a number of useful conversion factors. To make a conversion of an element in U.S. customary units to SI units, one multiplies the value of the U.S. customary unit, found on the left side in the table, by the equivalent value on the right side. For example, to convert 10 British thermal units to joules, one multiplies 10 by 1054.4 to obtain 10544 joules. 

This sometimee Is called the moment of inertia of a plane section about a specified axis. The exact conversion factor is 1.636 706 4 E-06. 

Use conversion factors to change the units of a measured quantity. 

Here, as in so many other cases, a conversion factor approach is used (Example 4.1).
