Beer-Lambert Law Calculator
Result
Beer-Lambert Law Calculator Apply the Beer-Lambert law to relate the absorbance of a solution to its concentration. Absorbance A = ε·b·c, where ε is the molar extinction coefficient, b the path length and c the concentration. Choose what to solve for — ab — free online calculator.
Formula
- Beer-Lambert Law Calculator calculates its result from C, Epsilon, B. It uses the formula A = epsilon * b * c, where A = absorbance, %T = 100 * 10^(-A). Change any input to recalculate the result instantly.
- The main inputs are C, Epsilon, B. Enter them in the units and format shown in the calculator.
- Use the units, labels and assumptions shown beside each input so the formula is applied consistently.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Beer-Lambert Law
- C: 2
- Epsilon: 3
- B: 4
Using C = 2, Epsilon = 3, B = 4, the calculated result is 24.
