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

> ./ book-us.epub book-si.epub


Conversion will be applied to all HTML files found in the epub archive. Currently detected units are:

  • inch
  • foot
  • yard
  • mile
  • ounce
  • pound
  • gallon
  • acre
  • square mile
  • degree Fahrenheit

Heuristics are used to avoid using too much precision in the output quantities, but this is currently very simplistic.
