Absorbance to Transmittance Calculator

Calculate Percent Transmittance from Absorbance

Formula

The formula to calculate the Percent Transmittance (T) from Absorbance (A) is:

\[ T = 10^{(2 - A)} \]

Where:

Absorbance to Transmittance Definition

Converting an absorbance to transmittance involves taking the antilog of 2 minus the absorbance.

Example Calculation

Consider an example where:

Using the formula to calculate the Percent Transmittance:

\[ T = 10^{(2 - 0.5)} = 10^{1.5} \approx 31.62\% \]

This means that the percent transmittance for this example is approximately 31.62%.
