How do I convert ETH to USD?
Type an amount in the ether row (or any other unit) and the USD row shows its live dollar value, refreshed every 60 seconds. Typing in the USD row converts the other way — dollars to wei, gwei, and ether.
How many wei in 1 ether?
1 ether equals 10^18 (1,000,000,000,000,000,000) wei. Wei is the smallest indivisible unit; ether is the canonical user-facing unit.
How many gwei in 1 ether?
1 ether equals 10^9 (1,000,000,000) gwei. Gwei is the unit gas prices are typically quoted in.
Why use BigInt instead of regular numbers?
JavaScript numbers cannot represent integers larger than 2^53 without precision loss. ETH balances exceed that — 1 ether is already 10^18 wei. Native BigInt arithmetic gives exact, EVM-faithful values.
What are kwei, mwei, szabo, finney?
They are intermediate denominations: 10^3, 10^6, 10^12, and 10^15 wei respectively. Sometimes called babbage, lovelace, microether, and milliether. Rarely used in practice but defined in the protocol.
