How do you calculate the air-to-fuel ratio for your engine? The **AFR (Air-to-Fuel Ratio) Calculator** can help you determine this important value with ease. Enter mass of air and fuel into calculator to find out AFR.

AFR stands for Air-to-Fuel Ratio. It is the ratio of the mass of air to the mass of fuel in an internal combustion engine. This ratio is important for the performance of engine, fuel efficiency, and emissions control.

To use the AFR calculator is simple . Here’s how you can do it:

**Enter Mass of Air (g)**: Input the mass of air in grams.**Enter Mass of Fuel (g)**: Input the mass of fuel in grams.**Enter AFR : 1**: Input the AFR value.

**Example Values**

For example:

**Mass of Air**: 14400 g**Mass of Fuel**: 1000 g**AFR**: 14.4 : 1

The formula to calculate AFR is:

$\text{AFR}=\frac{\text{MassofAir}}{\text{MassofFuel}}$

**Variables**

Variable | Description |
---|---|

Mass of Air | Mass of air in grams |

Mass of Fuel | Mass of fuel in grams |

AFR | Air-to-Fuel Ratio |

**Mass of Air**: 14400 g**Mass of Fuel**: 1000 g

** Calculation:**

**AFR**: $\frac{14400}{1000}=14.4$

Result: The AFR is 14.4 : 1.

**Mass of Air**: 12000 g**Mass of Fuel**: 800 g

**Calculation:**

**AFR**: $\frac{12000}{800}=15$

Result: The AFR is 15 : 1.
