🔢 Unit Converters Utility

Gwei, Wei, Ether & Satoshi Unit Converter

Accurately convert blockchain denominations without precision loss. Switch seamlessly between Wei, Gwei (nanoether), Finney (milliether), Ether, Bitcoin Satoshis, and hexadecimal calldata representations.

Quick Presets:
ETH (10⁰)
Gwei (10⁹)
Wei (10¹⁸)
Sats (~$3,000 equivalent)
Calldata & Hex Representation
0xde0b6b3a7640000
Hex (Wei)
Finney (milliether): 1,000 Finney
Kwei (babbage): 1,000,000,000,000,000 Kwei
Mwei (lovelace): 1,000,000,000,000 Mwei
EVM Note: Solidity smart contracts store all token balances in base atomic units (Wei with 18 decimals, or USDC with 6 decimals). Passing 1 ETH into an ERC-20 contract requires passing 1000000000000000000 Wei.
📐 Mathematical Formula & Verification Client-Side · Zero Cost · Deterministic
1 Ether = 10^9 Gwei = 10^18 Wei | Hex_Wei = toHex(BigInt(Wei))
