## Air to Fuel Ratio (AFR) Calculator Formula

The AFR can be calculated using the following formula:

AFR = (Air Flow / Air Concentration) / (Fuel Flow / Fuel Concentration)

## Illustrative Example

Let's consider an example to understand the practical application of the calculator. Suppose we have an air flow of 500 cubic meters per hour, a fuel flow of 50 liters per hour, an air concentration of 20%, a fuel concentration of 5%, a selected fuel type of gasoline, and a stoichiometric ratio of 14.7. By inputting these values into the calculator, we can determine the AFR.

Using the formula, the AFR is calculated as follows:

AFR = (500 / 20) / (50 / 5) = 125 / 10 = 12.5

## Therefore, the calculated AFR for this example is 12.5.Illustrative Table Example
