What does the unit millinit [mnt] represent?

Millinit [mnt] is a luminance unit equal to one-thousandth of a nit, used for describing very low brightness levels such as dimmed screens or indicator lights.

Why is the conversion done specifically at 555 nm?

555 nm corresponds to the photopic peak of human visual sensitivity, making it a standard wavelength for relating radiometric measurements to photometric luminance.

Can this conversion be used for wavelengths other than 555 nm?

No, this conversion applies only to measurements taken at exactly 555 nm, so it is not suitable for other wavelengths.
