Haha, apparently so.

In the Electrum window, you can click on "Tools" at the top, then "Preferences", then the "General" tab, and change you base unit from mBTC to BTC if you prefer. Under the "Fiat" tab, you can also enable "Show Fiat balance for addresses", so when you then click on the "Addresses" tab in the main window, it will show you the Balance in BTC or mBTC, as well as USD Balance in the next column.
