Conversions use exact standard definitions (e.g. 1 inch = 25.4 mm) computed in double-precision floating point, and results are shown with sensible rounding you can copy at full precision.
Does this tool need an internet connection?
Only to load the page the first time. The conversion itself is pure local math — no network requests are made.
Is this tool really free?
Yes — completely free, with no account, no watermarks and no file limits beyond what your device's memory can handle.
