Alcohol Units Calculator (Weekly)
Your week in UK units against the 14-unit low-risk guideline — drink-by-drink arithmetic.
The UK's 14-unit line is 'low risk', not 'no risk' — WHO's 2023 statement is blunt that no level is risk-free, with cancer risk starting from the first drink. The math everyone underestimates: a generous home-poured large wine is ~3 units, and a 650 ml strong beer nearly 4. Tracking a normal week honestly is usually more informative than any guideline.
