Frequently asked questions

What does Dishwasher Load Optimizer do?

Enter what needs washing to see how many cycles you need and whether the next load is full enough to run.

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.

Is there a tool for the next step?

Commute Life Wasted Calculator is the closest one after this: See how many hours, full days and years of your life your commute adds up to — and what you could have done instead.

What else is worth having open alongside it?

Dew Point Calculator and Diaper Size Calculator — they come up in the same task often enough to be worth a second tab.

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.

How-toHow Much Laundry Detergent to Use: Load Size First, Water Hardness SecondA normal medium load in a high-efficiency machine works out at 37 ml. Load size swings that threefold; water hardness only 1.28-fold — and the tool's hardness input carries no units at all. Here are the scales and the conversions it leaves out.ExplainerDew Point: What It Is, and How the Calculator Gets ItMagnus–Tetens with the Alduchov–Eskridge coefficients, 17.625 and 243.04. Why an absolute number beats relative humidity for judging comfort, what temperature a window has to reach before it runs, and the one input the calculator does not check.GuideWhat a Meeting Costs the Company, and What the Number Is ForSalary is not the cost. The ticker applies no loaded-cost multiplier of its own, so the rate box is where you have to put it. And the number is for one comparison: a recurring meeting against the written update that would replace it.ExplainerWind Chill: What the “Feels Like” Number Actually MeasuresThe calculator runs the 2001 index, not the 1945 one, and refuses to answer above 50 °F or under 3 mph. Here is what its number is a model of — bare skin, in shade, walking — and the two things it says nothing about: a clothed body, and a parked car.ComparisonWhich Fishing Knot Holds Best, and Why Every Published Table DisagreesKnot strength is quoted as a percentage of the line's rated breaking strain, and the percentages in circulation come from tests nobody agrees on. What the calculator on this page really stores, what one peer-reviewed measurement actually found, where a line breaks and why, and how to match a knot to its job.ExplainerWhat Remote Work Actually Saves, Once Heating Is CountedThe heating bill is real and it is small — about a fifteenth of the fuel a car commuter stops burning. The balance only goes negative in three identifiable cases, and one of them is a season ticket. Priced from Eurostat energy data, with the German tax system pushing the other way.
