About Unit Conversion
Unit Converter is a free online unit conversion tool that runs entirely in your browser. No uploads, no registration, no limits — just fast and accurate conversions.
It covers more than ten categories and hundreds of units: length, weight, temperature, area, volume, speed, time, data storage, energy, force, frequency, fuel efficiency, power, pressure and angle. Both metric and imperial systems are supported, using ISO-standard conversion factors for high precision.
Every calculation happens locally on your device. Values never leave your browser, so your data stays private. There is no account, no paywall, and no interruptive advertising blocking the tools.
The site is available in 14 languages: English, Simplified Chinese, Japanese, Korean, Spanish, Portuguese, French, German, Arabic, Hindi, Thai, Vietnamese, Indonesian and Russian. The interface, unit names and help content are translated for every language.
Every tool page includes conversion tables, popular conversions and step-by-step instructions for students, engineers, travelers and everyday users. Found an error or have a suggestion? Contact admin@unitconvert.world — we review and update data regularly.
