What Is a Unit Converter?

A unit converter allows you to quickly convert between different units of measurement. Whether it's length, weight, temperature, area, volume, speed or digital data sizes — simply enter a value and get the result instantly. All calculations happen directly in your browser without sending data to a server.

Supported Categories

This unit converter supports 7 categories: Length (km, m, cm, mm, mile, yard, foot, inch, nautical mile), Weight (tonne, kg, g, mg, pound, ounce, stone), Temperature (Celsius, Fahrenheit, Kelvin), Area (km², m², cm², hectare, acre, ft², in², mi²), Volume (liter, ml, m³, US/UK gallon, fl oz, cup, pint, quart), Speed (km/h, m/s, mph, knots, ft/s) and Digital Data (bit, byte, KB, MB, GB, TB, PB, KiB, MiB, GiB, TiB).

Tips for Unit Conversion

  • For digital data, pay attention to the difference between decimal (KB = 1000 bytes) and binary units (KiB = 1024 bytes).
  • Temperature conversions use special formulas — they are not based on simple multiplication.
  • Use the quick overview table to compare all units of a category at a glance.
