i cant remember the current sats per dollar, but i can remember the current btcusd value. 
There's 100 sats per ubtc (microbtc) and 1k multipliers up to one btc...
20000sats = 200ubtc = 0.2mbtc. 
Since btcusd is about $67000 now, 1 mbtc is about $67, so  0.2 is about $13.4
Easy huh? I should prolly add a memory location for the current sats per dollar value. 😉
