Quick Examples

How It Works

ERC-20 tokens on Ethereum and compatible blockchains store balances as unsigned integers. The decimals() function on the token contract specifies how many digits represent the fractional part. For example, a token with 6 decimals stores 1.5 tokens as 1500000 on-chain.

The formula is straightforward:

Human → Raw: raw = human × 10^decimals
Raw → Human: human = raw ÷ 10^decimals

Common Token Decimals

Token	Decimals	1 Token (Raw)
ETH / DAI / LINK	18	1,000,000,000,000,000,000
USDC / USDT	6	1,000,000
WBTC	8	100,000,000
SUI	9	1,000,000,000
GNO	18	1,000,000,000,000,000,000

Why Does This Matter?

Smart Contracts — Solidity has no native floating-point type. All token amounts are integers scaled by 10^decimals.
Precision — Using integers avoids floating-point rounding errors that could cause incorrect balances.
Interoperability — Wallets, block explorers, and dApps all need to agree on the decimal count to display correct balances.
