Pawel Premier 2025-07-11: Very good extension why is not supported shame on you google
Pierre-luc Lacasse 2025-03-17: Please update it!!! not working today. No longer supported. i use it every day. Best apps ever for convertion.
Vi Nguyen 2024-04-11: It's simple yet very handy to quickly convert units without opening a new tab or app. I just wish there was an option to save default units, or at least the last used conversions. It's also missing conversion options for pressure.
Andrej Bratuchin 2024-01-16: It does not keep last unit conversion. You need always select again.
Asheton 2023-09-09: Simple and effective. Even more so when I set the defaults in the settings menu. Would be nice if it saved the results across tabs.

Mike Ekim 2023-04-12: This just works. It has many different units to choose from and to convert to. Awesome extension. Whiners that are saying it don't have this or that need to chill . It free for God sakes. Write your own damn extensions if this is not what you want.

Jike Menkins 2022-08-06: 5/5 Love it. Use it frequently. Only request is please add force conversions for ft-lbs to in-lbs (some people can not figure out how to multiply or divide by 12) also please in-lbs to Newton-Meters

Digital Chimp 2022-02-06: Pretty handy. I know you can set defaults in the options but it also should at least remember what your last conversion was and not reset each time. Otherwise good.

Shawn 2021-08-20: A simple and handy converter to have in your extension toolkit. I appreciate that there is an option to change the "Default Category", however, it would be even better if it remembered the last used units. It is quite frustrating to have to change the units everytime the extension closes. For example, I might want to be doing "inches to mm" conversion, but everytime the extension closes, it will default back to "km to m", so I have to change the units (again) when I click on the extension. Arrrgh....

Alex DePillis 2021-07-23: Lots missing: pressure, density, flow. And this is the only unit conversion extension on Chrome with a significant number of users. Compare what this offers to this admittedly advertiser-driven website: https://www.convertunits.com/

Acorn 2020-12-30: Good unit conversion tool. PLEASE ADD PRESSURE CONVERSION. That would easily make this a 5 star extension.

Jc Arcilla 2020-10-16: I work as a Graphic Artist in my company and I always use this to convert the given measurement requirements for our billboards and posters. Very easy to use and straight to the point. Includes many units for conversion which is nice.

Anonymous 2019-10-24: It is a good extension, but there is an issue. It goes to the temperature option every a new page is loaded. It should stay on the last selected option.
travis gowen 2019-08-27: Just so great. So glad I had the options to change default category and units etc.

Meng-Hsiu Yu 2019-06-16: All are great now. Please add an right click conversion feature on text selection. It'd be the greatest of all.

Travis Nobles 2018-11-04: It RESETS every time you click out of it. This means that if you regularly convert oz to grams or anything like that, you have to go choose those every. single. time.

Masaaki Furuki 2018-08-02: Good design. But it always go back to temperature by start. Most used category should be there so I don't have to select category every time. Same things with unit. Most used unit should be come to the top. Or, last used category and unit when restart is better.

DogDoc713 2018-03-21: Very nice! I was looking for something that would work similarly to the old desktop gadgets, and this is the best I've found so far. A clean and simple way to quickly convert units. :-)
