Type converter in WPF Custom Control

I am creating a custom control in WPF and would like to have my converters in a separate resource dictionary to make things cleaner. I have a ControlStyling.xaml resource dictionary for the styling of my controls

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:DialIndicatorControl">

<Style TargetType="{x:Type local:MyDialIndicator}">
    <Setter Property="Template">
        <Setter.Value>
            <ControlTemplate TargetType="{x:Type local:MyDialIndicator}">
                <Border Background="{TemplateBinding Background}"
                        BorderBrush="{TemplateBinding BorderBrush}"
                        BorderThickness="{TemplateBinding BorderThickness}">

                    <Ellipse Width="{TemplateBinding BackgroundSizeRadius}"                                           

                    </Ellipse>
                </Border>
            </ControlTemplate>
        </Setter.Value>
    </Setter>
</Style>

A Converters.xaml resource dictionary where I would like to keep my converteres

<ResourceDictionary xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
                xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
                xmlns:local="clr-namespace:DialIndicatorControl">

<local:RadiusDiameterConverter x:Key="RadiusConvert"/>

And the Themes/Generic.xaml where I am pointing to both of these dictionaries.

<ResourceDictionary
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
xmlns:local="clr-namespace:DialIndicatorControl">

<ResourceDictionary.MergedDictionaries>       
    <ResourceDictionary Source="/DialIndicatorControl;component/Themes/Generic/Converters.xaml"/>
    <ResourceDictionary Source="/DialIndicatorControl;component/Themes/Generic/ControlStyling.xaml"/>
</ResourceDictionary.MergedDictionaries>

The problem I am having is when I place my converters in a separate resource dictionary my ControlStyling.xaml dictionary doesn't have a reference to the converters (which seems obvious now that I think about it). I thought that I would be able to use these converters since I merged both dictionaries in my Themes/Generic.xaml dictionary but that didn't work. Is there a good way to have all my converters in a separate dictionary and still be able to reference them in my ControlStyling.xaml for this custom control?

Reference the converter resource dictionary from the styling dictionary:

<ResourceDictionary.MergedDictionaries>       
    <ResourceDictionary Source="/DialIndicatorControl;component/Themes/Generic/Converters.xaml"/>
</ResourceDictionary.MergedDictionaries>
