A-Chassis Plugins Gui

[ikDebris]

I currently have a frame in the Plugins folder which is moved when the player gets in the car. How would I detect the exact speed of the vehicle in MPH and then print that value onto a TextLabel text?

[ikDebris]

local UNITS	= {
	{
		units			= "MPH"				,
		scaling			= (10/12) * (60/88)	,
		maxSpeed		= 230				,
		spInc			= 20				,
	},
	{
		units			= "KM/H"			,
		scaling			= (10/12) * 1.09728	,
		maxSpeed		= 370				,
		spInc			= 40				,
	},
	{
		units			= "SPS"				,
		scaling			= 1					,
		maxSpeed		= 400				,
		spInc			= 40				,
	}
}

while wait() do
	SpeedText.Text = math.floor(UNITS[1].scaling*script.Parent.Parent.Values.Velocity.Value.Magnitude) .. " "..UNITS[1].units
end
