Description by FENGTAO YANG Written by the developer, not by AppBrain. Click to read.
Convert All does one thing well: unit conversion, completely offline.

Pick a category, type a number, and see every result at once — no switching back and forth between "from" and "to".

CATEGORIES
• Length — mm, cm, m, km, inch, foot, yard, mile
• Weight — mg, g, kg, ton, ounce, pound, stone
• Temperature — Celsius, Fahrenheit, Kelvin
• Area — m², km², ft², yd², acre, hectare
• Volume — mL, L, m³, tsp, tbsp, cup, fl oz, pint, gallon
• Speed — m/s, km/h, mph, knot, ft/s

WHY THIS ONE
• 100% offline — works on a plane, in a basement, anywhere
• No ads, ever
• No subscription — pay once, keep it forever
• No account, no sign-up, no tracking
• Full precision — results are not rounded down to look pretty

Built for people who just want an answer and want it now.
