It's missing the megalithic yard and related units. http://www.ancient-wisdom.co.uk/megalithicyard.htm

This turns out to be a really cool system of measurement involving distance, volume, mass, frequency, etc, all based ultimately on the rotation of the earth.

Edit: the book Urial's Machine and its successors expand a great deal on this system of measurement, and how there are echos of it in Old English and Babylonian measurement systems. I can't find an online description, though.
