How many satoshis are in 1 Bitcoin?

There are exactly 100,000,000 (one hundred million) satoshis in 1 Bitcoin. A satoshi is the smallest indivisible unit of Bitcoin, named after its pseudonymous creator Satoshi Nakamoto. The full denomination hierarchy is: 1 BTC = 1,000 mBTC (millibitcoin) = 1,000,000 μBTC (microbitcoin/bits) = 100,000,000 satoshis. At a Bitcoin price of $60,000, 1 satoshi equals $0.00060 and 1 million satoshis (0.01 BTC) equals $600.

What is a millibitcoin (mBTC)?

A millibitcoin (mBTC) is one-thousandth of a Bitcoin (0.001 BTC or 100,000 satoshis). At a Bitcoin price of $60,000, 1 mBTC equals $60. Some exchanges and Lightning Network wallets display balances in mBTC to make small amounts easier to read. Similarly, a microbitcoin or bit (μBTC) is one-millionth of a Bitcoin (0.000001 BTC or 100 satoshis), worth $0.06 at $60,000/BTC.

Why does Bitcoin use satoshis instead of decimals?

Bitcoin's protocol is designed with integer arithmetic to avoid floating-point rounding errors. All Bitcoin amounts are stored and transmitted as integers in units of satoshis. The Bitcoin network never handles decimal BTC values internally — a transaction of '0.001 BTC' is processed as '100,000 satoshis'. This design ensures perfectly precise accounting across all nodes. As Bitcoin's price rises, satoshi denomination becomes increasingly useful for everyday transactions — the Lightning Network typically denominates payments in satoshis.
