Sobriety Calculator

A sobriety calculator estimates how alcohol might be distributed and eliminated; it does not measure blood alcohol concentration. The source model starts with fourteen grams per standard drink, multiplies by an alcohol-density factor of 0.789, and divides by body weight and a distribution ratio. It uses 0.68 for male and 0.55 for female selections. Food reduces the calculated initial value by twenty percent, while drink type is recorded but does not alter the arithmetic. The base elimination rate is 0.015 per hour. Age over fifty slows that rate by a factor of 1.05 and age over sixty-five by 1.1. The medications selection applies a factor of 1.15. Mild and moderate liver impairment apply factors of 1.2 and 1.4. The calculator divides the base rate by these factors, subtracts elapsed elimination from the initial estimate, and never displays a negative current value. Time to sober is current BAC divided by the adjusted rate. For fidelity, this page preserves the exact scaling found in the supplied source. Its displayed estimates are substantially lower than many conventional Widmark calculations because the source divides by one thousand while also displaying the result as a percentage. Therefore, never use this output to decide whether to drive, operate equipment, supervise others, swim, or undertake any safety-sensitive activity. A breath or blood test interpreted under applicable law is different from an online estimate. Alcohol absorption varies with serving size, alcohol concentration, drinking speed, food, body composition, metabolism, medication, and health. A standard drink is not simply any glass: cocktails, strong beer, and generous wine pours may contain multiple standard drinks. Alcohol can continue entering the bloodstream after the last drink, so an estimate may fall while measured BAC is still rising. Coffee, showers, exercise, food, and sleep do not rapidly remove alcohol; time is the primary factor. Signs of alcohol poisoning include inability to wake, slow or irregular breathing, repeated vomiting, seizures, pale or blue skin, and severe confusion. Call emergency services immediately and stay with the person. Do not assume someone can safely sleep it off. The legal threshold also differs by jurisdiction, driver category, age, and license type, and impairment occurs below statutory limits. The safest rule is not to drive after drinking. Arrange a sober driver, taxi, public transport, or a safe place to stay, and allow a generous margin beyond any calculated time.
