ui/gtk: don't try to redefine SI prefixes
Redefining SI prefixes is always wrong. 1s has per definition 1000ms. Remove the misnamed named constant and replace it with a comment explaining the frequency to period conversion in two simple steps. Now you can cancel out the unit mHz in the comment with the implicit unit mHz in refresh_rate_millihz and see why the implicit unit ms for update_interval remains.
