Last time I was at the speed shop trying to size a fitting in order to purchase an AN fitting they measured it with a caliper and told me what size it is -

Can someone tell me how to convert this?
I googled it and did not find anything helpful.

For a male fitting (IE i need a female fitting for it)
outside 13.85 mm or .545 in or 35/64"
inside 7.35 mm or .2875 in or 19/64"

For a Female fitting (IE I need a male fitting for it)
outside 18.90mm or .745 in or 3/4"
inside 14.50 mm or .570 in or 9/16"

For anyone who wants to know this is Toyota 4Runner Transmission cooler line.

I would like to know how to do this for future reference as well. Maybe there is a chart somewhere with corresponding sizes?

What about thread pitches?
