**Introduction**

Understanding the impact of alcohol on your body and the time it takes for your Blood Alcohol Content (BAC) to decrease is crucial for responsible drinking and safety. Our Bac Calculator Time Since Last Drink offers a simple way to estimate your BAC based on the time elapsed since your last alcoholic beverage. This tool is essential for individuals who want to make informed decisions about alcohol consumption and its effects on their body.

**Formula**

The calculation to estimate BAC based on the time since your last drink involves a linear decrease in BAC over time. The formula for this calculation can be described as follows:

Estimated BAC % = BAC % - (Time Since Last Drink * 0.015)

This formula takes into account that, on average, your BAC decreases by about 0.015% per hour. It provides an estimation of your current BAC based on the initial BAC and the time elapsed.

**How to Use**

- Enter your current BAC % in the designated field. (Note that this should be between 0 and 1, where 0.08% is the legal limit for driving in many places.)
- Input the time in hours since your last alcoholic drink in the corresponding field.
- Click the 'Calculate' button.
- The estimated BAC % will be displayed in the designated box below, providing you with the result.

**Example**

Suppose your initial BAC is 0.10%, and you want to estimate your BAC after 2 hours. Using the calculator, you will find that your estimated BAC is 0.0700%.
