Just for sake of completeness. AN Stands for Airforce Navy. the AN size is derived by multiplying the nominal (internal?) size of a hose by -16. So 1/2" hose equals 1/2"*(-16)=-8AN
so in my particular case -3AN equals a hose with internal diameter of 3/16"=0.1875"=4.7625mm

So it's a pointlessly complicated way of measuring something in 16ths of an inch?
I can't see the application of MIL standards to automotive.
