Gwei & Wei Unit Converter (BSC, ETH, Base, EVM)
A comprehensive cryptocurrency unit converter to instantly translate values between Wei, Gwei, Ether, BNB, and other fractional units for all EVM compatible blockchains.
Technical Info
All EVM-compatible chains (Ethereum, BNB Chain, Base, Polygon, Arbitrum, Optimism, Avalanche...) share the exact same gas calculation and subunit scaling.
Each chain defines its smallest base unit as Wei, and the native blockchain token (such as ETH, BNB, POL, AVAX) is mathematically equivalent to 10¹⁸ Wei.
Since the underlying arithmetic is fully identical, this single converter works seamlessly for all EVM networks without requiring network selection.

Wei, Gwei, and Blockchain Currency Subunits
Native coins on EVM blockchains (like Ethereum, BNB Chain, or Base) are split into smaller units to allow high-precision micro-payments for gas fees without floating-point errors:
What is Wei?
The smallest base unit of an EVM token (1 Ether = 10¹⁸ Wei). Smart contracts execute transactions in Wei to maintain arithmetic consistency and avoid rounding discrepancies.
What is Gwei?
Short for Giga-Wei (10⁹ Wei = 0.000000001 Ether). This is the standard unit used to measure network gas prices. When setting up custom transaction fees, you input values in Gwei.
EVM Uniformity
Because all EVM-compatible chains use the same Ethereum Virtual Machine specifications, their decimals match exactly. Thus, there is no need to switch networks for calculation.
Blockchain Subunit Reference Table
A comparative list of native coins, smallest units, and conversion ratios across top-tier EVM blockchains:

|---|---|---|---|
| Ethereum (ETH) | Ether | Wei | 10¹⁸ |
| BNB Chain (BSC) | BNB | Wei | 10¹⁸ |
| Base (ETH) | Ether | Wei | 10¹⁸ |
| Polygon (POL) | POL | Wei | 10¹⁸ |
| Avalanche (AVAX) | AVAX | Wei | 10¹⁸ |
| Arbitrum (ETH) | Ether | Wei | 10¹⁸ |
| Optimism (ETH) | Ether | Wei | 10¹⁸ |
Frequently Asked Questions about Gwei Converter
What is Gwei? How much is 1 Gwei in Wei and ETH?+
1 Gwei = 1,000,000,000 Wei (10⁹ Wei) and 0.000000001 ETH (10⁻⁹ ETH). In simple terms, it takes 1 billion Wei to make 1 Gwei, and 1 billion Gwei to accumulate 1 full Ether token.
Why isn't network selection required for EVM chains?+
All EVM-compatible networks scale units identically: 1 native coin = 10¹⁸ Wei. Since the ratios are 100% equivalent across Ethereum, BSC, Base, Polygon, and others, a single converter handles them all.
What do Szabo and Finney units represent?+
These are historic names for Ether units named after early cryptographers: Szabo stands for microether (10⁻⁶ ETH or 10¹² Wei); Finney stands for milliether (10⁻³ ETH or 10¹⁵ Wei). Standard client applications mostly display values in Gwei and native token amounts.
