Use the calculator above. Enter the game you currently play, your in-game sensitivity and your DPI, then choose Arma 3. It keeps your cm/360 the same, so the converted sensitivity feels identical to what you already aim with.
Most players use 400 or 800 DPI and set their in-game sensitivity from there. The DPI itself matters less than your cm/360, the distance you move the mouse for a full turn. Pick 800, set your Arma 3 sensitivity to land in the range above, and leave it alone.
