Calculating subject distance

Hi

I'm looking for an online calculator that calculates distance based on sensor size, focal length and magnification. I realize there are things that can affect this, like focus breathing and other inaccuracies, so it's only approximate and that's fine.

Does anyone know of one? I couldn't find any.

Thanks
