FAQ
Why is data storage converted in multiples of 1024 instead of 1000?
Computers use binary, so storage units traditionally use 1024 (2^10) as the multiplier: 1 KB = 1024 bytes. Some storage manufacturers use 1000 (decimal), which is why a '1 TB' drive shows as ~931 GB in your OS.
How accurate are the conversion factors?
All factors use full floating-point precision. For everyday use, results are accurate to at least 6 significant figures. Scientific applications may need more precise constants.
Can I convert between Fahrenheit and Celsius?
Yes. Temperature conversion is built in: F to C, C to F, C to K, and reverse. Temperature cannot be converted by simple multiplication — it requires offset formulas.
