Grocery Store

I primarily use this tool to convert between Pounds / Kilograms and Ounces / Litres when Im at a grocery store and confronted with units that dont match my shopping list. In this respect, it is indispensable.

In that respect, having a local application function without web access is critical, as cell reception tends to be spotty in my favourite grocery store.

It should support Power, though I doubt Id ever use Flow.

There are a few minor UI things that I would like changed, in order of importance:
1. In the Calculator view, when entering the number, the blue display at the top acts like an equals (=) button. It should also act as a Back button when the value is already a singleton (3) instead of a formula (1+2). This would provide a MUCH larger target to hit for the common use case of entering a number and returning to the comparison screen.
2. In the Select Unit view, the units are listed only by their full name (U.S. Fluid Ounces), but also seen by their short form (fl.oz.) elsewhere. I dont know both forms for some of the more exotic units, so its hard to find them when one only knows the short form. The Select Unit view should show both forms, with the latter right-aligned in the row.
3. In the Calculator view, when entering a formula, the blue display shows the entered values and operator (1+2). It would be very nice to enter an entire formula (eg: 1+2+3 Kg) and compute it all at once.
