About Crypto Subunits: Cryptocurrencies use integer arithmetic internally. What appears as "1 BTC" is actually 100,000,000 satoshis stored on-chain. Similarly, Ethereum uses wei (10^18 per ETH) and Solana uses lamports (10^9 per SOL).
Precision: This converter uses BigInt arithmetic to avoid floating-point rounding errors that plague standard JavaScript numbers. All conversions are exact.
Tip: Click any result row to switch to that unit as the input. The USD price field is optional and does not affect unit conversions.
