Frequently asked questions
Why is temperature handled differently from the other categories?
Length, mass, volume, speed, and area all convert with a simple multiplication factor — double the value, double the result. Temperature scales have different zero points, so converting requires an offset as well as a scale factor, which is why it can't share the same simple math.
How precise are these conversions?
Conversion factors used here match standard internationally recognized definitions (like the exact inch-to-meter relationship), so results are accurate to several decimal places for any practical use.
