Unit Converter - ATM

This is a big feature and polish update. New: • New Battery Charge category (mAh, Ah, coulombs) — now 16 categories in all • All Units view: see your value converted to every unit in a category at once, with one-tap copy • Copy and paste: tap a result to copy it, or paste a number straight into the input • Around 40 new units, including bits and binary data sizes (KiB, MiB, GiB, TiB), Imperial UK volumes, cubic feet and inches, carats, troy ounces, watt-hours, km/L, terahertz, nanometers, days and weeks • Live rate hint that shows the exact conversion factor, like "1 mi = 1.609 km" • A new animated swap button between the two rows • The app now remembers your last category and unit between launches • Hardware keyboard support on iPad Improved: • Redesigned landscape layout on iPhone and a cleaner, centered layout on iPad • Numbers now display using your region's decimal separator • Fixed two identical "mpg" entries in Fuel Efficiency — the Imperial one is now clearly labeled MPG UK • Better color contrast for easier reading in light mode • Improved VoiceOver support and larger, clearer keypad text at accessibility sizes • Input is now capped to prevent overflow, plus several small input-display fixes
