Please reorganize your extension as a TRUE SketchUp extension.
See: https://ruby.sketchup.com/file.extension_requirements.html

Also, take note of the various numeric conversion methods that the SketchUp API has added to the Numeric class. (You do not need to write your own conversion formulae.) Here is an example that will default to model units, if the unit argument is blank:

    def convert_to_inches(value, unit = nil)
      units = Sketchup.active_model.options["UnitsOptions"]
      if unit.nil? # use model units
        case units["LengthFormat"]
        when Length::Architectural, Length::Fractional
          return value.inch 
        when Length::Engineering
          return value.feet 
        else # Length::Decimal
          unit = units["LengthUnit"]
        end
      end
      case unit
      when :in, Length::Inches then value.inch
      when :m,  Length::Meter then value.m 
      when :cm, Length::Centimeter then value.cm
      when :mm, Length::Millimeter then value.mm
      when :ft, Length::Feet then value.feet
      when :yd, 5
        # NOTE: constant Length::Yard (5) was added for SU2020,
        #  use 5 to avoid NameError exception in older versions.
        value.yard # yards to inches
      else
        value.inch # if inches or unknown
      end
    end

Also, this is a good read for dealing with units in SketchUp:

Dealing with Units in SketchUp

There are extensions to the base classes in SketchUp’s Ruby API which often new SketchUp plugin developers overlook. If you aren’t aware of them you might find yourself reinventing many…
