What you can convert
Choose a category tab — Length, Weight, Temperature, Area, Volume, Speed, Time, or Data — then pick a source unit and a target unit. Enter any decimal number (commas are stripped). The result updates immediately, shows which unit you converted into, and displays a short formula line: for most categories this is the numeric factor relating one unit of the source to the target; for temperature it surfaces the familiar linear formulas when Celsius, Fahrenheit, or Kelvin are involved, otherwise notes conversion through Celsius as the internal pivot.
How conversions are calculated
Length, weight, area, volume, speed, and time all normalize to a single SI-style base value per category (meters, kilograms, square meters, cubic meters, meters per second, seconds, bytes) using fixed internationally agreed factors. Temperature first converts to Celsius, transforms, then converts out. Digital data treats one byte as eight bits and uses powers of 1024 for KB through TB, matching common operating-system reporting.
Tips panel and formatting
Below the converter, a bullet list per category reminds you of everyday reference points (for example US gallon to liters or mph to km/h). Very large or tiny magnitudes switch to scientific notation for readability. Use Swap to exchange the two units without retyping the value, or Reset to 1 for a quick sanity check.
