Method

How this calculator works

01

Choose amount-to-base or base-to-amount mode, enter a value, and specify token decimals.

02

CoinCalcs validates the manual inputs and applies this published model: base units = token amount × 10^decimals

03

The result is calculated locally in the browser and is not sent to CoinCalcs or a market-data provider.

Formula

The calculation

base units = token amount × 10^decimals
Example

A concrete scenario

1.5 USDC with 6 decimals equals 1,500,000 base units; 1.5 ETH with 18 decimals equals 1.5 × 10¹⁸ wei.

Known limits

What this estimate cannot guarantee

  • The tool does not look up a token contract, so the user must verify the correct decimals value independently.
  • The result is only as current and accurate as the assumptions entered in the form.
  • The output is educational scenario arithmetic, not financial, investment, tax, legal, or security advice.
