Why does the converter reject some inputs?
Wei must be a whole number. Gwei supports up to nine decimal places and ETH up to eighteen. Negative values and scientific notation are not supported. Inputs beyond this precision are rejected rather than silently rounded.
Can I convert in the other direction?
Yes. Choose ETH as the input unit and enter an amount to see its exact Wei and Gwei equivalents. Use Copy to get a result without thousands separators.
