How do you calculate yaw value?

For custom game what is yaw value, on youtube it was said it's dependent on FOV. Ok I know FOV so how do I convert it to yaw? thanks.

that is exactly what this software can do.
once you made it do perfect 360 in your game by pressing Alt [,
you put in your sens, it tells your game's yaw value.

i made a video about it, just watch.

everything is depends on the game, and all the software doing it just move your mouse for you, prefectly.
