Free BAC calculator and alcohol safety toolkit

BACwise is a free online blood alcohol concentration (BAC) calculator and alcohol safety platform designed for an international audience. It combines BAC estimation with country-specific alcohol limits, interactive tools, alcohol unit conversions, elimination estimates, and 113 evidence-informed guides covering alcohol metabolism, testing, medications, health effects, driving laws, and responsible alcohol use. BACwise requires no registration and is designed with a medically cautious approach: calculated BAC values are estimates only and should never be used to decide whether it is safe to drive.
