## Alcohol Burn-Off Rate Formula

The following two example problems outline the steps and information needed to calculate the Alcohol Burn Off Rate.

ABOR = BAC / T

- Where ABOR is the Alcohol Burn Off Rate (bac/hour)
- CBAC is the total change in BAC
- T is the total time (hrs)

To calculate the alcohol burn-off rate, divide the total change in BAC by the time.

## How to Calculate Alcohol Burn-Off Rate?

The following example problems outline how to calculate Alcohol Burn Off Rate.

Example Problem #1:

- First, determine the total change in BAC.
- The total change in BAC is given as: .020.

- Next, determine the total time (hrs).
- The total time (hrs) is provided as: 2.

- Finally, calculate the Alcohol Burn Off Rate using the equation above:

ABOR = BAC / T

The values provided above are inserted into the equation below and computed.

ABOR = .020 / 2 = .010 (bac/hour)

Example Problem #2:** **

For this problem, the variables required are provided below:

total change in BAC = .030

total time (hrs) = 3

Test your knowledge using the equation and check your answer with the calculator..

ABOR = BAC / T** = ?**
