UPDATE: I just read Harald Simon's review, posted on Jan 19, 2021, and saw that he is right. If you try to convert "90 feet" the conversion will be off by 17 inches. That's not very accurate. I did give this a three star review, but now I am dropping it to one star and uninstalling it. You can take your "10 day trial" and... keep it for people who make poor decisions. The unit converter might be good, might be bad. I like that I can just type something like "180 lb" or "72F" and immediately get a response showing the conversion. And I like that there is an option to remember my last input. But, the unit converter might also be limited. I haven't tested it enough yet. In other converters, you can convert things into dozens of other units but in this extension it seems there is only one unit you can convert to and it is chosen for you and I doubt that you can change it and even if you could it is too inconvenient. I really don't like how this extension is paywalled. Just allow us to use the currency converter for free and if people want to donate, they will. But not only that, the ONLY way to donate is through subscribing monthly, and I don't do subscriptions. If it were a one time and SMALL donation to unlock the currency converter, then I would maybe consider it. As for the time converter, that isn't at all useful to me. I can't like type "time Paris" to know what time it is there. It just shows my time. I can type "10 PM GST" and it will tell me how many hours ago that was, but that doesn't help me at all. I'd rather have the time converter paywalled and get the currency converter for free. Anyway, I really don't like paywalled stuff so I can't give this extension a rating higher than three stars. Remove the paywall, and I'll bump this up to four or five stars. If the currency converter is not paywalled, the developer can still have donation and subscription links and still receive an income for their work. But the way it is being done now is just going to result in unhappy people and poor reviews. Maybe some people want to spend $22-108 a year (depending on subscription plan) to convert currency when other extensions do it for free. Not me.

Great and fast works with inches to centimeters, f to c , highly recommended, should be a feature of chrome like opera has it.

I needed F to C, works pefect

Can you add knots to km and meters? Thanks

Very useful, should be a native feature of chrome. Now that it is free it is by far the best conversion extension I have used.

Great extension. Thank you for making all features free!

worked from the start, love stuff that just works!

How often was I in need of my phone or a web browser for converting units I usually don't use... I read about this extension in an article of a computer magazine. Idea great, extension works fast and reliable. Five stars!

Very helpful and works well for non-currency conversion. If you need currency conversion, you will have to pay for it with a reasonable price point. Reliable currency conversion APIs aren't for free and you are supporting the development of a reliable app.

Useless, does nothing until you pay for. Don't waste your time.

Does not work.
