What is Unit Converter?

Unit converter transforms measurements between different unit systems, supporting length, weight, temperature, data, time, area, and volume.

Supported Units

  • Length: meter, km, cm, inch, foot, mile
  • Weight: kg, g, lb, oz
  • Temperature: Celsius, Fahrenheit, Kelvin
  • Data: Byte, KB, MB, GB, TB
  • Time: second, minute, hour, day, week
  • Area: sq meter, hectare, acre
  • Volume: liter, gallon, cubic meter

Frequently Asked Questions

What standard do the length conversions use?
All units anchor to SI with exact legal definitions: 1 inch = 25.4 mm (by international agreement since 1959), 1 mile = 1609.344 m. The tool converts with exact constants, not approximations — safe for engineering and trade.
Why is temperature conversion not a simple multiplier?
Temperature combines an offset with a scale factor: °F = °C × 9/5 + 32. Zero degrees Celsius is not "zero temperature", so pure multiplication fails — unlike length or mass. This is the conversion people most often fumble mentally; use the exact result.
What is the difference between MB and MiB?
MB (decimal) is 10⁶ bytes — what drive makers quote; MiB (binary) is 2²⁰ = 1,048,576 bytes — what operating systems report for memory. A "500 GB" drive showing about 465 GB is unit mismatch, not missing capacity.
