+ Tweaked scientific notation to favor readability over accuracy. Scientific notation only shows up if the exponent is +9 or greater, or when it is -5 or less. When the exponent is -1 through -4, the number is now truncated at the 9th digit (ie. 0.0606060 instead of 6.060606x10^-2).
+ Added Rankine to temperature category (App Store user review request).
+ We now detect if the your locale settings have a preference for metric measurements. If yes, we use Litre and Metre. Substitutions also work for centimeter / centimetre, etc.
+ Fixed bug where label swap was appearing on the viewable side of the right wheel, when viewing currency units.
+ Other minor bug fixes and improvements

Gets the job done
Converts any units I could possibly need to know quickly and easily, which is all I'm asking for from a conversion app. I hate the fact that there are ads and banners all over everything. You cannot click on a function without an app popping up. Most ads are annoying enough to nix only one star, but this one goes above and beyond.
Good app, stable, helpful
This replaced my former iPhone-designed conversion app. Pretty much no frills, but the user interface is intuitive, simple and effective. I like that it instantly converts...for example, input 5 kilometers and then rotate the other wheel through feet, miles, etc...you'll see the program instantly calculate the different conversions. This is more convenient than my last app, which required you to hit "enter" each time.
Cons...not many. Would like the units to be alphabetical (light years between kilometers and miles). Would also like large numbers to display better...how many miles is 2.5 light years? 1.277e13 isn't that helpful...you then have to figure out if that's trillion, tens of billions, etc. but these are small complaints...no one needs to know how many miles are in two light years, and this converts my English measures to my friend's French metric perfectly.
A few improvements are needed
The program is OK, BUT it would be a lot better if remembered where you were last at. For instance on exchange rates it always goes back to Brazil. It would be great if it recalled your last conversion
With Family Sharing set up, up to six family members can use this app.
