I like the site.

Unfortunately for this American, having a different set of standards for mathematical notation tripped a "don't these people know the difference between Hz and kHz?" impulse in my brain.

To illustrate: When an American sees "50,000 Hz" we process it as you would process "50 000 Hz". This misunderstanding could be corrected by using two or four significant figures after the decimal. That's too much to ask though, probably requiring a large number of hours to accommodate someone not even from there.

Your site is fine, it's our brains that are more appropriately adjusted. A little disclaimer link or something would help a number of us understand. A large number of otherwise intelligent and educated Americans don't realize this difference in notation and this would be a great opportunity to educate them.

The site is confusing, even as a European: both periods and commas are used as decimal separators.

SI allows either but the document should be consistent. Thousands separators are a half width space.

"The decimal marker shall be either the point on the line or the comma on the line. The decimal marker chosen should be that which is customary in the context concerned."

I am European and I dislike the use of comma, too, and I use dot everywhere. I see it as "50 000" as well, as a non-American. :P

Yes good point! We only had the idea of making this site a few days ago so the UI could use some tweaks. Thanks for the feedback.

UPDATE: made a small PR and fixed it. For now it's most consistent to just use dot separators everywhere.

Especially when the number format on the dial doesn't match the number format on the chart.

AFAIK it's entirely possible to adjust it based on the browser's locale
