What to include

To get a useful answer quickly, tell us:

• Reporting a wrong result? The tool, the exact numbers you entered, what it showed, and what you expected.
• Something broken? Your browser and device, and what you'd clicked just before.
• Suggesting a tool? What you're trying to work out and how you currently do it. The problem is more useful than the proposed solution.
• Reporting an ad? A screenshot and the page it appeared on. We can report specific advertisers to Google.

Common questions we can answer here

Can I use these tools on my own site?

Link to them freely — no permission needed. Embedding or copying the tools themselves isn't permitted; see the terms of use.

Do you store what I type into the tools?

No. Everything runs in your browser and nothing is transmitted to us. The privacy policy covers what we do and don't collect.

Can I advertise on the site?

Advertising is handled entirely through Google AdSense — we don't sell placements directly, and we don't accept paid links, sponsored posts or guest articles.

Will you link to my site?

Only if it's genuinely useful to readers of a specific page. We don't do link exchanges and we don't accept payment for links.
