to support the community in conversion of bitcoin units we had implemented a simple website CalcBitcoin. The new site should support you in any question regarding bitcoin units. Fit currencies as USD, EUR and CAD are supported, too.
We are open and happy to get any feedback or requests to improve our service.

While I like what you did/attempted to do, I think things like dBTC and cBTC are only going to confuse people. Not to mention these have never been used (to my knowledge) in the Bitcoin world. You need to add "bits," too.
