About Unit Converter
Convert between units across eight categories — length, weight/mass, temperature, area, volume, speed, time and digital storage. Pick a category, enter a value and choose the from and to units; the result is instant, and an 'all units' panel shows your value in every unit of that category at once.
Conversions use precise standard factors (and the correct affine formula for temperature), so results are accurate for everyday and technical use. Everything runs locally in your browser; nothing is uploaded.

Frequently asked questions
Which units can I convert?
Length, weight/mass, temperature, area, volume, speed, time and digital storage — including both metric and imperial units, and decimal vs binary data sizes (KB vs KiB).
How accurate are the conversions?
They use exact internationally-defined factors (for example 1 inch = 0.0254 m) and the proper temperature formulas, then trim floating-point noise for display.
What's the difference between KB and KiB?
KB is decimal (1000 bytes) while KiB is binary (1024 bytes). Both are offered so you can match whichever a given tool or OS uses.
Is anything uploaded?
No. All conversions happen locally in your browser.
