Ok how do I translate these numbers to distance from mirror?

It's not distance to mirror, it's the focal length. The focal length of our eyes is static

The "focal length" of our eyes is a subjective number, because our retinas aren't flat and our attention doesn't cover our whole field of view at the same time.
