Convert length, weight, temperature, area, volume, data, speed and time — all in your browser.
The Unit Converter switches values between units across length, weight, temperature, volume, and more, giving you an accurate result instantly — no need to remember conversion factors.
It's a everyday helper for cooking, travel, science homework, and engineering back-of-the-envelope work.
Each category defines the ratios between its units relative to a base unit, so the converter scales your value into the base and back out into the target — the standard approach that keeps conversions consistent and reversible. Temperature uses its specific offset formulas rather than simple ratios.
Conversion is instant and local, so you get a precise answer without any lookup or upload.
