An\ -example of this is time. Whether tracked in terms of minutes, hours\ -or days, it should be possible to convert between the various forms.\ -Doing this requires the use of commodity equivalencies.\ -\ -For example, you might have the following two postings, one which\ -transfers an hour of time into a @samp\{Billable\} account, and another\ -which decreases the same account by ten minutes. The resulting report\ -will indicate that fifty minutes remain:\ -\ -@smallexample\ -2005/10/01 Work done for company\ - Billable:Client 1h\ - Project:XYZ\ - \ -2005/10/02 Return ten minutes to the project\ - Project:XYZ 10m\ - Billable:Client\ -@end smallexample\ -\ -Reporting the balance for this ledger file produces:\ -\ -@smallexample\ - 50.0m Billable:Client\ - -50.0m Project:XYZ\ -@end smallexample\ -\ -This example works because ledger already knows how to handle seconds,\ -minutes and hours, as part of its time tracking support. Defining\ -other equivalencies is simple. The following is an example that\ -creates data equivalencies, helpful for tracking bytes, kilobytes,\ -megabytes, and more:\ -\ -@smallexample\ -C 1.00 Kb = 1024 b\ -C 1.00 Mb = 1024 Kb\ -C 1.00 Gb = 1024 Mb\ -C 1.00 Tb = 1024 Gb\ -@end smallexample\ -\ -Each of these definitions correlates a commodity (such as @samp\{Kb\})\ -and a default precision, with a certain quantity of another commodity.\ -In the above example, kilobytes are reporetd with two decimal places\ -of precision and each kilobyte is equal to 1024 bytes.\ -\ -Equivalency chains can be as long as desired. Whenever a commodity\ -would report as a decimal amount (less than @samp\{1.00\}), the next\ -smallest commodity is used. If a commodity could be reported in terms\ -of a higher commodity without resulting to a partial fraction, then\ -the larger commodity is used.}
