In practice, one usually multiplies T by 100 to obtain the percent transmittance (%T) , which ranges from 0 to 100%. %T = T * 100. If the T of a sample is 0.40, the %T of is 40%. This means that 40% of the photons in the incident light emerge from the sample as transmitted light and reach the photodetector.
