You're casting the value argument as an int and then not using it.

I imagine what you're looking for is something like (deriving from IMultiValueConverter rather than IValueConverter):

public object Convert(object[] values, Type targetType, object parameter, CultureInfo culture)
{
    double totalPacketsSent = (double)values[0];
    double totalPacketsInList = (double)values[1];

    // further validation for handling divide by zero, etc. may need to go here

    return totalPacketsSent / totalPacketsInList * 100
}

And in the XAML:

<Controllers:Gauge x:Name="gauge" Minimum="0" Maximum="100">
    <Controllers:Gauge.Value>
        <MultiBinding Converter="{StaticResource GaugeValueConverter}">
            <Binding Path="(my:MyClass.TotalPacketsSent)" />
            <Binding Path="(my:MyClass.TotalPacketsInList)" />
        </MultiBinding>
    </Controllers:Gauge.Value>
</Controllers:Gauge>
