Beer-Lambert Law Calculator

Calculate the absorbance $A$ using the formula: $$ A = \varepsilon \, c \, l $$

* Ensure that the units are consistent (e.g., $\varepsilon$ in L/(mol·cm), $c$ in mol/L, and $l$ in cm).

Step 1: Enter Input Parameters

Molar Absorptivity, $\varepsilon$ (L/(mol·cm)):

e.g., 100 L/(mol·cm)

Concentration, $c$ (mol/L):

e.g., 0.01 mol/L

Path Length, $l$ (cm):

e.g., 1 cm
