FAQ
- What is a gwei and why is it used for gas prices?
- Gwei (gigawei) equals 1,000,000,000 wei. Gas prices on Ethereum are typically quoted in gwei because wei values are very small. A typical gas price of 20 gwei = 20,000,000,000 wei = 0.00000002 ether.
- What is the smallest Ethereum unit?
- Wei is the smallest Ethereum unit, named after Wei Dai, the cryptographer. 1 Ether = 10^18 wei. All Ethereum transactions and smart contracts internally use wei for maximum precision.
- Why does this tool use BigInt?
- Ether amounts converted to wei can exceed JavaScript's safe integer limit (2^53 - 1 ≈ 9 quadrillion). BigInt handles arbitrary-precision integer arithmetic, ensuring accurate conversions for large or very small values without floating-point errors.
Enter a gas price value and select the source unit (wei, gwei, or ether) to instantly see conversions across all Ethereum denomination units: wei, kwei (1e3), mwei (1e6), gwei (1e9), microether (1e12), milliether (1e15), and ether (1e18). Uses BigInt arithmetic for full precision on large wei values.
