 Not only that, I discovered today (the hard way) that you can combine
 them:
 
    % units
    537 units, 41 prefixes
 
    You have: hG
    You want: 1
            * 1e+11
            / 1e-11
    You have: myrianano
    You want: 1
            * 1e-05
            / 100000
 
 Normally, "ha" is a standard abbreviation for "hectare", but to units
 it means "hectoatto".
 
 Very broken.
