5/5A personal favorite
I got the free version to use at work when needing to convert metric measurements to English and back again. I liked it so much, I upgraded to the paid version, which I like even more. It saves units I've used as favorites automatically. If I'm just trying to impress someone by showing them how many millimeters in a light year or how many teaspoons in a bushel, favorites are easy to edit. It's useful in unexpected ways, like converting units used on TV so I get what they are saying. Edit: You can now round your answer to fractions, up to 1/64. There is a color palate if you want a different background. Adjustable font size in case you have vision issues. Plus a host of advanced options. For instance, if you are not American or just preferred British spellings, you can even switch to that. It's almost a shame I already rated this 5 stars, as I cannot give it a "raise."

5/5Very good unit converter
This is a really good unit converter. Been using this for years and haven’t found anything I like better to this day. It has a vast amount of conversion options, and it allows you to make bookmarks for conversions you use frequently. You can also export those bookmarks and then import them back in if you need to reinstall app. I use this app everyday and it’s never let me down. It’s been very stable in MacOS Sequoia. My only wish is iCloud support for syncing of data so I don’t have to export and save the file manually, and so that data will sync between MacOS and iOS versions of the app.

5/5Best Conversion App
Update to review below: In my original review, I mentioned that the app did not support 64 bit number base conversions. Within several days of my review, the app was updated to provide 64 bit support. Not only is the app easy to use and accurate, the developer is very responsive to user requirements. I would give this app 6 stars if possible. Previous review several days ago: This app is the absolute best for unit conversions. It is intuitive and quite easy to use. Excellent user interface. I like the new number base conversions, but my only criticism is that is doesn’t handle more that 32 bits. Even the CPUs in modern iPhones are 64 bit. Please add this capability.

5/5Excellent
I have used quite a few converters and this is the one that I nearly always use. It has a very plain, almost boring interface (a benefit, as it is 100% function) but easy to use. It converts multiple different units quickly. There is no messing around with setting what units you want or don't; just enter an amount and start typing your units and they pop up. I got this for free, but would gladly pay $1-2 (I'm not sure of the price).

5/5I’d be lost without this tool
I own a homebrew store that sells wine and beer supplies. I have people who bring in old and foreign recipes to make. Without this converter I might as well close. It not only gives an answer, but it shows the formula to derive the answer - which I share with customers so these people can do it themselves before they come in and take up my time. Before this app I never knew there was a conversion for some of the measurements I’ve encountered. Thanks.
