About Converters
This collection has 128 ready-to-use tools for converters. Every tool runs in your browser, so the numbers you type are not sent to a server. Each page explains what to enter, shows the formula or method behind the result, and gives worked examples you can compare against your own figures.
Results are estimates for planning and comparison. Where rates, thresholds or rules change from year to year, the tool page states the tax year or assumptions it uses. Check them against an official source before you file, pay or sign anything.

Converters FAQ
How accurate are these unit converters?
Each converter uses the exact published definition of the unit, such as 1 inch = 2.54 cm and 1 lb = 0.45359237 kg. Results are exact apart from display rounding.
Do the converters use US or imperial units?
Each page names the system it uses. Volume units differ most: a US gallon is about 3.785 litres and an imperial gallon is about 4.546 litres.
Can I convert in both directions?
Yes. Most converters link to the reverse conversion, and every page shows the formula so you can invert it by hand.
