The MultiBit website mentions Bitcoin amounts being showns as "mikes":
Everybody has a different way of wanting to display their balances and this is especially true when dealing with different countries and languages. Users of MultiBit HD can now fine tune their own display to exactly match what they want. Support is in place for millis, mikes and satoshis along with different presentation styles including the icon, "BTC" and "XBT".
What is a "mike" and why is it named such?
