Simple Unit Converter Offline gives you a unit converter for length, weight, temperature and 9 more categories, and it needs no signal. You only ever need a conversion in the middle of something else. The recipe is waiting, the drawing is open, the homework is half done, and a web search for "cups to ml" buries the answer under ads and recipe blogs. By the time you find it, you've lost the thread, and tomorrow you'll search the exact same thing again.
This simple unit converter answers while you type. Open it, pick a category, and the result updates with every keystroke: no convert button, no page load, no scrolling past sponsored results. Your last 50 conversions stay one tap away, so the pairs you use every day (the same metric-imperial switch, the same oven temperature) replay instantly instead of being typed again.

Copying a very large or very small result (like 1 eV in joules) now gives a plain number that pastes back into the app as the same value, instead of a different one.
Pasting a number with thousands separators, like 1,234,567 or 1.234.567, now reads it as one million instead of 1.2.
The keyboard no longer sits on top of the bottom banner while you type.
Opening a category no longer interrupts you with a full-screen ad.
