As we know One lm/(m²·sr) is equal to 1 cd/m² (1 lm/(m²·sr) = 1 cd/m²).

To convert Lumen/Square Meter/Steradian to Candela/Square Meter, multiply your lm/(m²·sr) figure by 1.

Example : convert 25 lm/(m²·sr) to cd/m²:

25 lm/(m²·sr) = 25 × 1 cd/m² = cd/m²

To convert Candela/Square Meter to Lumen/Square Meter/Steradian, divide your cd/m² figure by 1.

Example : convert 25 cd/m² to lm/(m²·sr):

25 cd/m² = 25 ÷ 1 lm/(m²·sr) = lm/(m²·sr)
