About Unit Converter
All the unit conversions that come up regularly — in one place, with real results. Seven categories: length, weight, temperature, volume, area, speed, and digital storage. Temperature uses the actual formulas (not naive linear factors), so Celsius, Fahrenheit, and Kelvin all convert correctly. Data sizes handle both decimal (MB, GB) and binary (MiB, GiB) units because yes, they're different and it matters. Type a value and the result updates immediately — everything runs locally in your browser, no server needed.

Frequently asked questions
Which unit categories are covered?
Length, weight, temperature, volume, area, speed, and digital data size — each with the metric and imperial units people actually use day to day.

Yes, no limits — everything runs in your browser.
