Frequently asked questions

What is Sobriety Calculator?

Track your streak since a quit date, with money saved, units avoided and milestone badges for alcohol, smoking or any habit.

When would I actually use this?

The questions no reference answers: what a meeting is costing while it runs, how many hours a commute has taken out of a year, how much detergent a load actually needs, and a few that exist for the pleasure of knowing — how many popcorn kernels would fill a room, what a hamster generates.

What is the most common mistake?

Quoting the playful ones as if they were measurements. A room filled with popcorn and a salary counted in bathroom breaks are arithmetic done honestly on premises chosen for fun; the number that comes out is exactly as solid as the assumption you fed it, which is the joke.

What else is filed next to it?

Clothing size converter, Commute Life Wasted Calculator and Dew Point Calculator share its section. They are not variants of it — being filed together is not the same as being alike — but that is where to look if this turned out not to be the tool you wanted.

Where do the figures come from?

The household ones follow the figure printed on the packet or the manufacturer's chart, which is why a detergent dose or a nappy size may not match another brand's. The rest state their assumptions on the page, because assumptions are the whole content of the answer.

ExplainerHow Long Until You Are Sober? Zero-Order Elimination ExplainedAlcohol leaves the body at a roughly constant mass per hour, whatever the concentration. That one property — zero-order elimination, unlike caffeine's exponential decay — explains why doubling the dose doubles the time, why nothing speeds it up, and why every estimate carries a wide error bar. With the Widmark relation worked through, and each market's legal limit stated separately.ExplainerThe Calories in a Drink Are Mostly the AlcoholEthanol carries 7 kcal per gram and the arithmetic is exact: volume × ABV × 0.789 × 7. A dry spirit is almost pure alcohol calories; a liqueur is nearly half sugar. Here is the derivation, the table, and the metabolic caveat stated without overclaiming.ExplainerWhat a Standard Drink Actually IsA standard drink is a defined mass of ethanol — and the definition changes at the border. The same glass of wine is 1.28 drinks in the United States, 1.79 in France and 2.28 in the United Kingdom.ExplainerOne Bust, Five Numbers — and Only the Collar Is a MeasurementA 34-inch bust is a US 6, a UK 10, a German 36, a French 38 and an Italian 42. Five labels, one body — while a men's shirt collar prints the neck measurement itself.ExplainerThe Same 38 Is Ten Millimetres ApartA women's EU 38 is a 245 mm foot; a men's EU 38 is a 235 mm foot. The printed number is a label, not a measurement — and on the children's US scale it goes backwards, where a 1 is bigger than a 13.GuideNappy Sizes Overlap, and the Smaller One Usually WinsAt 7.5 kg a baby is inside both the size 2 and the size 3 band. Take the 2: a snugger fit leaks less. The step to watch for is the weight at which the smaller band ends, and at 7.5 kg that is eight and a half months away.
