I just recently installed this app and thus far it is excellent. Easy to use and the ads are at the bottom and do not disrupt or distract from using the calculator.

What good is copy if you can't paste? Also, it doesn't let you just simply copy what you calculated. Instead, it adds a bunch superfluous text that slows down your original cause. The reason I downloaded such an app was so I wouldn't have to do so many things manually and waste more time on a task.

Bad, liter is a capacity not a volume. Really bad conversion science and the operation of the converter in the app is terrible and not functional to an answer at all. My wife teaches math, she said litre is not metric volume, it is metric capacity. An example of volume is cubic meters. Getting an answer out of the app for conversion I found to be impossible, I suggest your page design is illogical.
