RVR to SM formula....
Used to have a very easy formula for converting RVR to statute miles, one that could be done in your head. Now I can't remember it, can anyone help me out?
Think you took the first two numbers of an RVR (1600) and divided by some number??????????

The FAA has assigned conversion values which do not have a very good mathematical correlation to each other. I know these off the top of my head...
1SM / 5000
3/4 SM / 4000
1/2 SM / 2400
1/4 SM / 1600
You can use reported vis instead of RVR for CAT-I and non-prec approaches only. CAT-II/III require RVR.
