Note: All these BAC calculator software estimate your blood alcohol content level as per the input. That means the results shown by these software are estimations and your actual BAC level might vary from the results. This is because the alcohol content in your blood depends on various parameters like recent food consumption, body hydration status, weight, kidney function, gender, age, and most importantly the amount & beverage of the alcohol intake. So, do not blindly rely on the results to confirm your sobriety level to drive or work.
