DayZ is updated, there's a new config file and the FOV can now only be set in-game.

m_scopedSensitivity is missing from the calculator but it is in the config file of the game

There is an option in the calculator to choose either in game or use the config file for setting your sensitivity and fov, if you set your fov in game it uses vdeg and if you use the config file it uses multiplier - as DPI Wizard said
 
I attached a screenshot to show you the tab to choose in game or config file in the calculator.

Also the calculator tells you which fov type the game is using, you don't need to set it yourself.

Happy new year everyone!
A new update was just published that adds a few new features:
Favorites - Click the star next to the game in the calculation output to add it to your favorites.

Favorites will appear in the top of the game list for easier access.

  Reverse calculation - You can now easily reverse any calculation by clicking the reverse icon between the games.

This will swap the "convert from" to "convert to" and preserve all converted data. This makes it easier to see if everything matches up, but note that: Aim calculations will be different if hipfire is matched using 360 distance and the hipfire FOV is not the same, since you change source. Any discrepancy due to rounding limitations will be carried over, which might make the reverse different.
  A new conversion method called "Jedi's Trick" is added.

More info in this thread, but it basically uses the average distance between monitor distance 0% and 100% for both axis.
