About Token Decimal Converter
ERC-20 tokens and tokens on other blockchains store balances as large integers without decimal points. The number of "decimals" defined in the token contract tells wallets and apps where to place the decimal point for display. For example, USDC has 6 decimals, so a raw balance of 1000000 represents 1.000000 USDC. ETH and most ERC-20 tokens use 18 decimals, so 1 token is stored as 1000000000000000000.
This tool converts in both directions: give it a raw integer and the number of decimals, and it shows the human-readable amount. Or give it a human-readable amount and it returns the raw integer you would pass to a smart contract function. It uses arbitrary-precision arithmetic to handle the very large numbers common in blockchain development without floating-point errors.
