Everyday Tools (1286)
Most of life's arithmetic is small: convert the unit, count the days, split the bill, pick a password that survives a breach list. Individually trivial — but each deserves a tool that states its constants instead of rounding in the shadows.
This shelf holds the everyday half of ToolDune: length, weight, temperature and data conversions; date arithmetic and live countdowns; random generators and the hardware sanity checks (keyboards, microphones, screens).
Bottom line: no account, no ads wall in the middle of the answer, no cookie banner theatre. Pick the tool, get the number, get on with your day.

Frequently asked questions
Do the converters use exact factors?
Yes — each tool shows the exact relationship it applies (for example 1 inch = 25.4 mm by definition since 1959), so results are exact at any scale rather than a rounded lookup.
Do countdowns work for next year?
Yes — the countdown timers roll over automatically to the next occurrence of the date, so a page is always accurate no matter when you open it.
Are the generators safe to use for passwords?
The password generator uses the browser's cryptographically secure randomness and never transmits the result. It is as safe as the device you generate it on.
Is there a full list of every tool?
Yes — the All tools section on the homepage lists everything by category, and the footer of every page carries the full site matrix.
