Shoe size converter

EU, UK, US and Japanese shoe sizes side by side for women and men, each row tied to the foot length in millimetres — the one figure that does not change from brand to brand.

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.

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.

They sit next to each other but answer different questions: Clothing size converter is the one to open when you need it to tops, bottoms and shirt collars converted separately between FR, IT, DE, UK and US — each with the body measurement EN 13402 makes its primary dimension. Pick whichever matches what you're starting from — both are free.

Diaper Size Calculator is the closest one after this: The right nappy size for your baby's weight, how many you'll use, and when to size up.

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

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.
