Given absorbance, how do you calculate %transmission from this?

Question

I know to find absorbance the equation is absorbance= 2=log%T.

But, how do I solve THIS equation?
%T= ?

(basically I forgot how to take the inverse log or whatever)

Sorry, that first equation should be:
Absorbance= 2-log%T



I'm looking for this equation to find %transmittance of light values for a spectrophotometer.

Answer 1

if absorbance = 2-log(%T), log(%T) = 2 - absorbance
If the log in the equation is base-10, then
%T = 10^(2 - absorbance)
Your formula seems to agree with the ref, which quotes the Beer-Lambert Law as:
(decadic) absorbance = -log10(T) which would = 2-log10(%T)
