Tools & calculators
Every calculator here shows its inputs, its formula, the intermediate steps, the assumptions it makes and where it stops being reliable. A single number with no working is a black box, not a tool.
What BeerHQ will not build
There is no blood-alcohol estimator and no “how many can I have and still drive” tool. Individual alcohol elimination varies too much for any calculator to support that inference, such tools are used precisely when judgement is impaired, and being wrong once is catastrophic. The units calculator reports what is in a drink and makes no claim about its effect on anyone.
