Frequently asked
How accurate are the conversions?
Factors follow the standard SI definitions and NIST-published conversions. Precision is IEEE-754 double-precision floating point (~15 significant digits).
Why is there a separate Temperature section?
Temperature uses affine transformations (offsets like +32 for Celsius→Fahrenheit), not just multiplicative factors. Everything else is factor-based and shares the same math.
What about KB vs KiB?
KB is 1000 bytes (decimal, used by disk manufacturers and networking). KiB is 1024 bytes (binary, used by RAM and operating systems). Both are provided; use whichever your context demands.
