Description
Free blood alcohol content (BAC) estimator using the modified Widmark formula. Enter weight, standard drinks or serving size and ABV, and time since the first drink for live estimates and approximate time to zero. Calculations run in the browser without an account. Includes BAC reference guides. Educational estimates only; not a measurement or a way to decide whether it is safe to drive.
No-Login Task
"Estimate BAC and approximate time to zero, compare standard drinks, and read BAC reference guides without signing up."
Editorial Review & Verification
Hands-on VerifiedAdults, health educators, event planners, and designated drivers seeking a private, zero-account blood alcohol content (BAC) estimator to model alcohol elimination timelines and sober times before social outings.
Interactive geometric construction, algebraic function graphing, calculus visualization, and STEM mathematics education.
+ Key Strengths (Pros)
- ✓ Zero registration required with instant reactive updates across weight, gender, and beverage parameters
- ✓ Uses the peer-reviewed Modified Widmark formula incorporating sex-specific body water distribution constants
- ✓ Dynamic visual gauge rendering immediate blood alcohol percentage curves and time-to-zero milestones
- ✓ Confirmed zero network egress: sensitive health, weight, and alcohol intake inputs remain entirely in browser memory
− Limitations (Cons)
- − Lacks dedicated export controls for downloading or copying BAC curves to clipboard
- − Provides educational approximations only and cannot replace certified breathalyzer hardware or legal sobriety determinations

CADES 2.0 Route A dogfooding verified in ego-browser Chromium. Navigated to drunkcalc.org and tested the live BAC simulator with a baseline of 180 lb body weight. Toggled gender from Male to Female, observing the reactive circular gauge adjust instantaneous blood alcohol content from 0.046% to 0.064% based on Widmark distribution volume formulas. Added additional beverage entries with 0ms long task freezes and 0.00 CLS. Audited network activity, confirming 0 outbound payloads across the entire session.
