About BAC-CALC.COM
The honest, transparent blood alcohol estimator built for public safety and harm reduction.
Why We Built This Site
Most blood alcohol calculators on the web suffer from two serious problems: they give users false precision (displaying an exact number like 0.041% as if human physiology were a static math formula), or they serve as thinly veiled lead-generation funnels for private rehabilitation centers and lead-aggregators.
BAC-CALC.COM was built to provide an honest alternative: a tool that models metabolic ranges (accounting for individual variation in alcohol dehydrogenase enzymes and gastric absorption), highlights the time until alcohol is eliminated, and never pushes aggressive marketing, account sign-ups, or invasive tracking scripts.
Our Core Editorial & Safety Principles
- Zero False Precision: Human alcohol metabolism varies by ±25% or more. We show typical estimates alongside realistic metabolic boundaries (low to high).
- Never Claim It Is Acceptable to Drive: We will never state or imply that someone has cleared alcohol sufficiently to operate a vehicle. Even low alcohol levels measurably impair cognitive and motor functions.
- Client-Side Privacy: What you drink is your business. All calculations happen entirely in your web browser. No drink logs or personal measurements are sent to our servers.
- Primary Sources Only: Every formula, elimination rate, and statutory limit is sourced directly from peer-reviewed scientific journals or official government transport agencies.
Funding & Commercial Independence
We do not accept referral fees or lead-generation payments from rehab providers, law firms, or treatment networks. The site is planned to be supported by display advertising served by third parties.
Editorial & Correction Policy
We do not fabricate credentials, clinical boards, or user numbers. Content is written and maintained by independent technical researchers who cross-reference primary sources from the National Highway Traffic Safety Administration (NHTSA), National Institute on Alcohol Abuse and Alcoholism (NIAAA), the UK Department for Transport (DfT), and seminal pharmacokinetic papers.
