## What is Unit Converter & Dictionary?

An app that both converts units and works as a dictionary explaining what each unit means. Useful for everything from converting units in class to checking currency before a trip abroad.

■ A wide range of conversion categories
• Length, area, volume, mass, speed, temperature, angle, pressure, energy, power, force, density, fuel economy, data size, and more
• Includes lesser-known units too — traditional Japanese units, imperial units, nautical miles, carats, horsepower

■ Unit dictionary
• Search across unit names, aliases, and symbols
• Look up how a unit is pronounced, its rough scale, and fun facts
• Jump straight from a search result into conversion mode

■ Currency conversion
• Real-time currency conversion using up-to-date exchange rates

■ Built to be easy
• Conversion and dictionary lookups work entirely on your device (only currency conversion needs a connection, to fetch exchange rates)

■ AI support (Premium)
• Just ask the AI "what unit is this?" or "convert X to Y" — it handles switching categories and running the conversion for you

■ Premium plan
• Unlimited AI support
• Ads removed

Good for: converting recipe measurements, studying science and math, or checking currency and units before an overseas trip.
