Short background on the units used in this conversion.
Bitcoin (BTC) is the base unit of the Bitcoin protocol — one whole coin on the ledger. This converter uses fixed denomination factors only, not live market prices or fiat exchange rates.
Whole bitcoin amounts appear in balances and summaries; smaller denominations like satoshi are used for precise on-chain amounts.
Millibitcoin (mBTC) equals 0.001 bitcoin — one thousandth of a BTC. A fixed denomination factor, not a price quote.
mBTC can express mid-range amounts without long decimal strings of satoshi.
mBTC = BTC × 1,000BTC = mBTC × 0.001, using the same exact factors as this converter.
