Bitcoin conversions
The right value.
The right representation.
Convert Bitcoin units and inspect encodings with explicit inputs and clearly labeled results.
Convert BTC & satoshisConvert BTC and satoshis
One BTC equals 100,000,000 satoshis. The BTC to satoshi converter handles the two units locally without passing money values through floating-point arithmetic. Choose the input unit, enter an amount and review the exact result. Check units before copying a value into another tool.
Estimate a fiat amount using your own price
The BTC to fiat calculator uses the BTC price and currency code you supply. It rounds to two decimal currency units and does not fetch a live exchange rate. Its estimate excludes trading fees, spreads and later price changes.
Inspect witness address encoding
The Bech32 and Bech32m tool encodes or decodes Bitcoin witness addresses with network, witness-version and checksum checks. Review the network and payload context. A valid encoding does not establish control of an address.
Treat private-key encodings as secrets
The Base58Check tool runs locally because encoded values can contain private keys. Base58Check and WIF are representations, not encryption. Decoded private-key output remains sensitive and must never enter a public lookup, URL or contact message.
Validation before use
Read each tool’s accepted format, intended network and limitations. Keep secret results private and clear them when finished. For public address checks, use the Bitcoin address validator rather than assuming an encoding alone proves the destination is correct.
