Crypto Unit Converter: BTC to Satoshi, ETH to Gwei and Wei
Convert cryptocurrency amounts between their units exactly: bitcoin, millibitcoin, bits, and satoshis; ether, finney, szabo, gwei, mwei, kwei, and wei; and SOL and lamports. Every unit is shown at once, with an optional value at a price you type in.
Crypto Unit Converter: BTC to Satoshi, ETH to Gwei and Wei: Amounts are converted with whole numbers of the smallest unit, so there is no floating-point rounding: 0.0015 BTC is 150,000 satoshis, and 21 gwei is 21,000,000,000 wei or 0.000000021 ETH. An amount with more decimals than the smallest unit allows is rejected rather than silently rounded. Runs 100% locally in your browser with zero server file uploads.
