Wei to gwei and ETH converter

Convert Ethereum units with exact integer arithmetic.

Your inputs

Values stay in this page. Use the units shown beside each field.

Enter a nonnegative decimal. ETH allows up to 18 decimal places, gwei up to 9, and wei must be a whole number.

Result

Enter your values, then calculate. You can also load the worked example.

Your result will appear here.

Convert Ethereum denominations without rounding through a floating-point number. One ETH is one billion gwei or one quintillion wei.

How the calculation works

1 ETH = 1,000,000,000 gwei = 1,000,000,000,000,000,000 wei.

Worked example

Example: 1.000000000000000001 ETH equals exactly 1000000000000000001 wei. One gwei equals 1000000000 wei.

How to use the result

Enter the amount as plain decimal text without commas or exponent notation. Exact results retain very large integer values.

A fractional wei is rejected. To calculate a transaction fee, combine a gwei-per-gas price with gas used in the separate gas calculator.

What this result leaves out

  • This changes units only. It does not fetch ETH prices or estimate transaction gas.
