Great app for converting measurements!

Great app! I use this app ALL THE TIME to convert measurements for volume, length, etc.. especially when looking to purchase items that are typically measured in cm or mm by vendors and I am more familiar with inches. Similar for liquids, going from mL to tsp.

So easy to use!!! I've tried other conversion apps like this and the others never felt as easy to use and intuitive as this app. Just select measurement type, enter amount in keypad, then ALL options are calculated...just scroll to find the one you need!

Free version has ads, but they never get in the way of calculations! Ads are only on the bottom of the screen. Personally, I am more apt to check out ads if they DONT get in the way of using the app!

Very helpful app

Thanks for the team developing this helpful app. But it need some improvement like filtering by just the two units you want to convert to and from with another filter of only the unit class for better view. Any way excellent work and keep going.

Easy to use, simple

I use the converter at home, great for baking recipes, and at work when working with multiple measuring systems. All the most basic and frequent units are available, and even a few more.
