What is a Unit Converter?
A unit converter translates measurements from one unit to another—like converting miles to kilometers, pounds to kilograms, or Fahrenheit to Celsius. It eliminates the need to remember conversion formulas and handles the math instantly.
With different countries using different measurement systems (metric vs. imperial), a unit converter is essential for international travel, online shopping from foreign sites, or working with instructions in unfamiliar units.

Common conversion scenarios:
- International recipes — Converting cups/tablespoons to grams/milliliters
- Travel planning — Understanding distances in km when you think in miles
- Online shopping — Converting clothing sizes between EU/UK/US systems
- Weather apps — Converting Celsius to Fahrenheit or vice versa
- DIY projects — Converting metric hardware specs to imperial or reverse
