FAQ
- What are all the Ethereum denomination units?
- Ethereum has 7 named denominations: wei (1), kwei/babbage (10^3), mwei/lovelace (10^6), gwei/shannon (10^9), szabo (10^12), finney (10^15), and ether (10^18). The names honor pioneers in cryptography and computer science.
- When would I use szabo or finney?
- Szabo (1 microether = 10^12 wei) and finney (1 milliether = 10^15 wei) are rarely used in practice today. Historically they were used in early Ethereum tooling. Modern development primarily uses wei, gwei, and ether.
- How does this tool handle very large numbers?
- Converting ether to wei produces numbers up to 10^18, which exceeds JavaScript's safe integer limit. This tool uses BigInt for integer arithmetic and string formatting to display large values accurately without scientific notation or precision loss.
Enter a value in any Ethereum denomination and instantly see conversions across all seven standard units: wei, kwei (babbage, 1e3), mwei (lovelace, 1e6), gwei (shannon, 1e9), szabo (1e12), finney (1e15), and ether (1e18). All results are copyable. Uses string-based arithmetic for full precision.
