Count CaloriesBlood Alcohol Content (BAC) is the percentage of alcohol in your bloodstream. It's the standard measurement used worldwide to determine alcohol impairment and legal intoxication levels.
In most countries, the legal BAC limit for driving is 0.08%. However, impairment begins at much lower levels, and commercial drivers often have stricter limits of 0.04%.
BAC is influenced by body weight, gender, food consumption, drinking rate, and individual metabolism. Our calculators account for these variables for accurate results.
These calculators are for educational purposes and general awareness. Individual responses to alcohol vary significantly. Always err on the side of caution and never drive after consuming any amount of alcohol.
