What does lumen/square foot/steradian represent?

It is a luminance unit quantifying visible light per unit area per solid angle, typically used with U.S. customary area units.

When should I use millinit [mnt] units?

Millinit is suitable for describing very low luminance levels, such as dimmed screens or low-brightness instrumentation lights.

Is this converter suitable for high brightness values?

Millinit is designed for low luminance; for very bright measurements, other units or scaling methods may be necessary.
