Just set the FOV to Vertical (1:1) and use the same value (86).

You can try to use the same conversion for hipfire as your ADS and scopes: https://www.mouse-sensitivity.com/?share=6d0061b61632e557e421e98084031850

Set the ADS and scope scale to 99.083: https://www.mouse-sensitivity.com/?share=17de5bb30efe2973a47d30d9f48c41bf

x and y are still different, but they have halved the x sensitivity so they are much closer. I've updated it now

What you said is correct, and it has to be this way to make any sense. If the scopes were matched to the hipfire of the output game you would not get any consistency unless you also match the hipfire FOV between the games.
Consider this example converting from Overwatch with FOV 103 to Overwatch with FOV 80: https://www.mouse-sensitivity.com/?share=43c8dace9347072001b6b2962b254eaf
The FOV change only affects hipfire, the zoom FOV stays the same. So the sensitivity (360 distance) for the zoom should also stay the same to keep it consistent. If they were matched based on FOV 80 instead, you would get a completely different sensitivity for identical zoom levels.
Click the reverse calculation button between the input and output game

The "Zoom Level: Iron Sight" is also 1.25x, at least on the weapons I've tried so far. Just switch between 1.25x and iron sights and you'll see it's the same.
There might be a 1.00x somewhere, but it's really hard to find!

Good idea, I've added it to the "Actual VFOV" line in the advanced output now!

Also note that aspect ratio usually does not change the 360 distance (with some exceptions), so converting between different aspect ratios will in most cases result in the same sensitivity when using 360 distance.

Yes, you need to match the conversion setup to your game settings. For CSGO this means setting ADS and Scope to MDV 133.3333% and Scale 100%. This will calculate the zoom sensitivity to "1" for all scopes. When converting to any other game, the same conversion will be applied, preserving the exact same sensitivity based on the FOV of the scopes.

For hipfire you can either to the same, or keep it at 360 distance, depending on your preference.

This is on my todo list!

You need to change the Multiplier 1 value to what you want to use, in most cases you can just use the same value as Mouse Horizontal Sensitivity

It is taking into account any discrepancy.

That's the accuracy of the robot I use to test, so if you can notice that you are literally more accurate than the robot
So no, you can't notice that. It doesn't hurt to get the sensitivity as accurate as possible though, but I wouldn't worry about anything less than a millimeter.

It works for everything except Gunner Aim Sensitivity (Look only, it works for Zoom) and Transport Vehicle Freelook Sensitivity.

Absolutely, this works exactly like with the scopes; you keep the same tracking speed.

This is the vertical movement (it has the same wording as horizontal, can be a bit confusing). The horizontal movement is 6.096 cm. To match the crosshair to edge movement to this, set the Windows / 2D conversion setup to MDH 100%: https://www.mouse-sensitivity.com/?share=edd8d784fe94306bef13d4810207d608
Advanced mode is selected here, so you can see in the bottom of the Valorant calculations that MDH 100% is equal to 3.0495 centimeters mouse movement as you want it

They scale it to the 4:3 FOV like CSGO etc, so MDV 133.3333%.

Ok, I see what you mean now. There is no reason why, it's just different ways of implementing this.

Enter the correct resolution
The calculator tries to auto-detect your resolution, but for some reason your browser is reporting 1943x2087, which is definitely not correct.

PUBG scales the sensitivity to MDH 100%. Meaning that half the FOV is twice the 360 distance distance etc.
This is not the same as the Viewspeed calculations, they work in a completely different way than a fixed monitor distance, so what you are seeing is expected.
If you want to set up the calculator to match how PUBG works (so you get the same value for all aims), set the ADS and Scope conversions to Monitor Distance Horizontal 100%.

Some games are missing the FOV range and rounding precision since they were added before this was supported by the calculator. Doom 2016 is one of these games.
Doom Eternal and Half-Life one are registered with no decimal support though. You can still enter multiple decimals, but if you use the Auto FOV function, or switch the FOV Type to the default from another FOV Type, the rounding will be applied.

Then you have to set the ADS and Scope conversions to 360 distance, but know that this will make aiming extremely hard at higher zoom levels as the crosshair will skip several pixels, and a lot of games does not even support a sensitivity this high for the scopes.
You are not preserving any kind of aim consistency doing this, you are only conserving the consistency of turning an amount of degrees, say turning 180 degrees to look behind you (which you generally don't do with a 12x scope etc).

If you are not configuring the game according to the FOV that Auto FOV gives you, the calculations will be wrong.
So you should always use the same FOV in the calculator as you have in the game, or else the calculations will be incorrect.
