Editorial policy

These are the rules we follow when we publish a calculator or an answer.

• What we publish. Calculators, converters and short worked answers. Every page shows the byline Calculators Free Editorial Team.
• Show the working. Each result is followed by the steps used, so it can be checked.
• No invented numbers. A fixed number (a conversion factor, a boiling point) appears only if it is a standard definition. Anything that depends on a place or a person, such as a tax rate, is entered by you.
• No false credentials. We do not say a page is reviewed by an expert or fact-checked unless a named person did it.
• Advertising. The site shows advertising. Advertisers do not influence what we write.
• Corrections. When we or a reader find an error, we fix the page. See Corrections.
• Not advice. See the Disclaimer.
