Since one nit is one lumen/m^2/sr, I wonder if square meter * steradian gives us something meaningful? Say, could it be a measurement of something?

My way to think about it is to imagine a square with area A illuminating its surroundings. To measure the "illuminating ability", whose unit is Candela, per unit area of that square, we have to divide the Luminous intensity of the square as a whole by its area A.
