Straight answers to ordinary questions

How much a fridge weighs. How loud a vacuum cleaner is. What a 502 error means. How many teaspoons are in a tablespoon. Plain answers, with the figures cited, and no scrolling past six paragraphs of preamble to reach them.

How this site works

Every page is built from a structured dataset rather than written one at a time, which is how a small site can cover this much ground. That approach earns its keep only if the numbers are right, so every figure carries a source, and where the honest answer is a range rather than a single value, the range is what you get.

There are no accounts, no newsletter, and nothing to install. Pages are static files, so they load immediately and keep working with JavaScript switched off.
