BNB is the native coin of the BNB Chain: 1 BNB = 1,000,000,000,000,000,000 wei, and 1 wei = 0.000000000000000001 BNB. As an EVM chain, BNB Smart Chain keeps balances in wei exactly as Ethereum does — the same atomic ladder, carrying BNB instead of ETH. To convert BNB to wei, multiply by 1,000,000,000,000,000,000 — move the decimal point 18 places to the right. Or skip counting zeros: type the amount into the converter above — it uses exact integer arithmetic, so nothing is ever rounded. Converting the other way? See Wei to BNB.
