Metricize detects uses of many types of legacy units in an ebook and converts them to the SI (metric) equivalents.
Example: In order to convert an book-us.epub to book-si.epub run the following
> ./metricize.py book-us.epub book-si.epub
Conversion will be applied to all HTML files found in the epub archive. Currently detected units are:
- square mile
- degree Fahrenheit
Heuristics are used to avoid using too much precision in the output quantities, but this is currently very simplistic.
