How to report a wrong figure or a broken page.

Reporting a wrong figure
This is the most useful message you can send. Please include the address of the page, the number it showed, and the number you expected — the third part matters, because most reports turn out to be a US versus Imperial difference, or a decimal megabyte against a binary one, and knowing which figure you were expecting identifies that immediately.
Requesting a unit or a converter
Say which unit and, if it is not obvious, what you were trying to work out. Units that are ambiguous in ordinary speech — barrels, tons, cups — are added as explicitly labelled variants rather than as a single averaged entry, so the use case is worth describing.
Everything else
Same address. There is no contact form, deliberately: a form would need spam handling and would store your message somewhere, and email already works.
