# Bitcoin Conversions — BTC, Satoshis, Fiat & Encoding

> Convert BTC to satoshis exactly, calculate fiat values from a supplied BTC price, and inspect Bitcoin Bech32 or Base58Check encodings locally.

Convert BTC and satoshis with exact local arithmetic. Fiat conversion uses a supplied price and does not fetch a live exchange rate. Bech32/Bech32m and Base58Check tools inspect representations with their documented validation. WIF and private-key encodings are secrets, not encryption.
