Linear units convert through a shared base unit. Temperature uses offsets instead of a single multiplier. Digital data labels make the decimal KB/MB and binary KiB/MiB distinction explicit.
Which units does this converter support?
It covers common length, mass, temperature, area, volume, speed, time, and digital-data units, including metric and US customary choices. Each category updates its own From and To lists.
Why are KB and KiB different?
Decimal storage uses powers of 1,000: 1 KB is 1,000 bytes. Binary storage uses powers of 1,024: 1 KiB is 1,024 bytes. The labels stay separate so a disk or download estimate is easier to check.
Are the conversions sent to a server?
No. The factors and formulas are bundled in the page, and the value stays in this browser tab. No account, upload, or live API is required.
