Convert between Wei and ETH using the exact factor of ten to the eighteenth power, the number of Wei in a single ether. Wei is the smallest indivisible unit of Ethereum and the unit that smart contracts, RPC responses and transaction data actually use under the hood. Because the numbers get huge, this converter uses arbitrary precision so a value like 1500000000000000000 Wei maps cleanly to 1.5 ETH with no floating point drift. Type into either field and the other updates instantly. This is useful when you are reading raw contract calldata, decoding an event log, or checking a balance returned by a node in base units. Everything is computed locally in your browser, so nothing is uploaded and the full 18 decimal precision is preserved.
