From asb to lm/(ft²·sr):
As we know One asb is equal to 0.0295719561 lm/(ft²·sr) (1 asb = 0.0295719561 lm/(ft²·sr)).
To convert Apostilb to Lumen/Square Foot/Steradian, multiply your asb figure by 0.0295719561.
Example : convert 25 asb to lm/(ft²·sr):
25 asb = 25 × 0.0295719561 lm/(ft²·sr) = lm/(ft²·sr)
To convert Lumen/Square Foot/Steradian to Apostilb, divide your lm/(ft²·sr) figure by 0.0295719561.
Example : convert 25 lm/(ft²·sr) to asb:
25 lm/(ft²·sr) = 25 ÷ 0.0295719561 asb = asb
As we know One lm/(ft²·sr) is equal to 33.815821889 asb (1 lm/(ft²·sr) = 33.815821889 asb).
To convert Lumen/Square Foot/Steradian to Apostilb, multiply your lm/(ft²·sr) figure by 33.815821889.
Example : convert 45 lm/(ft²·sr) to asb:
45 lm/(ft²·sr) = 45 × 33.815821889 asb = asb
To convert Apostilb to Lumen/Square Foot/Steradian, divide your asb figure by 33.815821889.
Example : convert 45 asb to lm/(ft²·sr):
45 asb = 45 ÷ 33.815821889 lm/(ft²·sr) = lm/(ft²·sr)
