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.
Satoshi (sat) is the smallest standard Bitcoin denomination — 0.00000001 bitcoin (10⁻⁸ BTC), named after Bitcoin's pseudonymous creator. Fixed factor, not a market price.
Satoshi is the precision unit for on-chain amounts and fee calculations — 100,000,000 satoshi always equals 1 bitcoin.
sat = BTC × 100,000,000BTC = sat × 0.00000001, using the same exact factors as this converter.
