1 Lot if Bitcoin = how much actual BTC

If for example the BTCUSD price is currently 47,000 and I trade 1 Lot of BTC can i determine how many BTC that actually is? Are there a 100,000 units in a BTC lot? My calculations don’t seem to make sense.

I know there are plenty of pip calculators and lot size calculators but that’s not what I am looking for. I want to know what 1 lot of BTC would mean in actual Bitcoins. Thank you.

I’m not sure crypto is measured in lots?
