Not really familiar with Doge, so someone else will have to help. Best to think of BTC not as each individual BTC, but as Satoshis, or SATs. When you get rid of the decimal, it makes everything easier. So 1btc = 100mil SATs. Since 1usd is 2200 SATs at the moment, you just do some basic math.
Hopefully you find someone knowledgeable about Doge. Good luck in your transaction
