We've released two simple tables with unit prefixes (like kilo, mega, micro, etc.): the SI prefixes table and similar one for IT purposes the binary prefixes table.
Also one more IT calculator added: calculator of bandwidth (internet connection bandwidth) - it supports even exotic units of bandwidth like peta-bytes per day.
A small celebration for us: we've just crossed 50 working calculators ! Next milestone is 100 - stay with us !
