Base Unit Converter
Instantly convert Base amounts between ETH and its smallest unit, the Wei. On Base, 1 ETH = 10^18 Wei, so a single rounding mistake can be costly — this tool keeps every denomination exact.
* Base is an Ethereum L2. It uses ETH as its native gas token with 18 decimal places (1 ETH = 1018 Wei).
Understanding Base units
The native asset of Base is ETH, divisible into 18 decimal places. The smallest indivisible unit is the Wei. Smart contracts, RPC responses, and on-chain transactions almost always use Wei, while wallets and exchanges display ETH — converting between them correctly is essential for developers and traders alike.
