Unit Converter
Convert length, mass, temperature, volume, area, speed and data.
About this tool
A single converter for everyday units: length, mass, temperature, volume, area, speed and digital data. Pick a category, type a value, and every unit in that category updates instantly.
How it works
Every category is defined by conversion factors to a single base unit. Temperature uses linear formulas with offsets. Data uses powers of 1024. The live table computes each unit from the base value and shows results in a compact, sortable layout.
How to use Unit Converter
- 1Select a category such as Length or Temperature.

Examples
1 mile converts to 1.609 kilometres.
20°C is 68°F and 293.15 K.
2 GB converts to 2048 MB or 2048000 KB.
Pro tips
- Temperature uses correct offset formulas, not just a scale factor.
- Data units use binary (1024) multiples, the standard for storage.
- Use the copy icon on any row to grab a result for email or chat.
Frequently asked questions
Which unit categories are supported?
Length, mass, temperature, volume, area, speed and digital data — each with 4 to 12 common units.
Are the conversions exact?
Conversions use internationally defined factors. Displayed values are rounded to 6 significant figures for readability; copying always uses the most precise value.
Why does 1°C not equal 33.8°F exactly in reverse?
It does — temperature is linear but not proportional, so the zero points matter. The tool applies the correct formulas in both directions.
