Bitcoin unit questions
What are the units of Bitcoin?
One bitcoin (BTC) is 1,000 millibitcoin (mBTC), 1,000,000 microbitcoin (bits) and 100,000,000 satoshis (sats). Sats are the smallest unit recorded on the blockchain.
How many sats are in one bitcoin?
Exactly 100,000,000 sats. That number is fixed by the protocol and never changes, unlike the fiat exchange rate.
What is a millibitcoin or a bit?
A millibitcoin (mBTC) is 0.001 BTC, or 100,000 sats. A bit (µBTC) is 0.000001 BTC, or 100 sats. Both were common before sats became the default unit.
Which unit should I use for everyday prices?
Sats. A coffee priced at 0.00004 BTC is easier to read as 4,000 sats, which is why wallets, Lightning invoices and the Satuno extension default to sats.
Which currencies does this converter support?
US dollars, Mexican pesos, euros, Colombian pesos and Argentine pesos, using a live rate from the public CoinGecko API.
