## What is Unit Converter?

「Unit Converter」· Everyday and pro unit conversion.
「Fast · Offline · Precise」

「Unit Converter」turns length, weight, temperature, area, and volume into the reading you need. Open a category, enter a value, pick from and to units, and see results refresh instantly. Swap direction in one tap. Most conversions run on device, so trains, flights, and weak networks still work. Search units by name or symbol when lists get long. A dedicated number pad cuts keyboard switching; finishing an entry saves history automatically. Tune precision from 0–6 decimal places for rough estimates or finer checks. Favorite a category plus from/to pair, browse history by today, yesterday, and earlier, and reopen the last combo fast. Currency rates, BMI, time zones, baking cups, shoe sizes, and fuel economy expand when you need them. Unlock advanced categories and organization with a one-time purchase instead of renewing forever.

「Unit Converter」also shows recent categories on home so length, weight, and temperature stay one tap away. Temperature uses scale formulas; date offsets help trip planning; radix covers binary through hex. Fuel economy respects regional habits; shoe charts help cross-border shopping; baking maps cups to grams. Favorites stay searchable after unlock. Rates refresh online or use cache offline. Homework, job sites, and packing share the same pick-units → result → reuse flow.

——— Key Features ———
1  Instant two-unit conversion
   · Enter a value, choose from and to units, and get results immediately; swap direction without re-picking every field
   · Search long unit lists by name or symbol; the numeric keypad finishes entry, shows the result, and writes history
   · Adjust 0–6 decimal places for everyday estimates or finer readouts; temperature uses scale formulas, not naive ratios
2  Favorites and history reuse
   · Save category plus from/to pairs as favorites for metric/imperial and kitchen repeats without rebuilding the screen
   · History groups today, yesterday, and earlier so one tap restores numbers and units from a prior session
   · Search favorites by unit, category, or group name; grouping and bulk tidy unlock with the one-time purchase
3  Lifestyle and pro categories
   · Free everyday coverage includes length, weight, area, volume, temperature, time, speed, and data storage
   · Lifestyle tools cover currency rates, BMI, time-zone offsets, baking cups and spoons, percent, angle, and radix
   · Pro packs add fuel economy, international shoe sizes, pressure, torque, illuminance, and more via one-time unlock

——— Real-World Scenarios ———
· Travel shopping: metric/imperial and shoe charts offline first; check before WhatsApp or Instagram
· Kitchen and baking recipes: convert cups, tablespoons, and teaspoons to grams or milliliters with less mental math
· Trips across time zones and currencies: compare city offsets and major FX pairs; refresh online or fall back to cached rates
