Use quick tools with clear inputs

Everyday conversion and percentage tools are most useful when the starting figure, unit and time period are clear. Run a second scenario if an input is uncertain, and keep the original figure alongside the converted or calculated result for an easy check.

Check the unit and time period before entering a number.
Keep rounding consistent when comparing results.
Use a second scenario to test any uncertain assumption.

Name the unit, then calculate

The miscellaneous hub is for the "tools that don't belong anywhere else" but turn out to be the most-used calculators on the entire site — percentages, currencies, dates, tips, discounts. They solve the small questions that arrive while you are doing something bigger.

These are the calculators you reach for at the grocery till, while planning a trip, or when a colleague asks "what's 12% of £450?". Each one does one thing precisely and quickly, without the complexity of the finance or tax tools.

Because these tools are used in short, transactional visits, the site is deliberately light on them — no intrusive overlays, no forced sign-ups. The formulas are simple, standard, and identical to what any scientific calculator would produce. The value is speed and clear presentation of the answer.

Start with Percentage or Unit Converter for the most common cases, Date Difference or Age for time questions, and Tip or Bill Splitter when you are out with friends. Currency Converter uses cached daily rates — for live FX, check an official provider before any transaction that actually matters.
