A Finney is already a unit of 10 satoshis according to the Bitcoin Wiki.

Hmm but that doesn’t seem right. If we were to use a similar 100 base system to make the easiest transition for people, it would need one less decimal place as a BTC/Satoshi is 100 million, the BTC/Finney should be 1 million not 10 million to match. Right?
