Frequently asked questions
Why is temperature handled differently?
Most units convert by multiplying a ratio, because zero means the same thing in both. Temperature scales have offset zero points, so Celsius to Fahrenheit needs both a multiplication and an addition.
Are data units based on 1024 or 1000?
This tool uses 1024, so 1 KB is 1,024 bytes — the convention in operating systems and file sizes. Storage manufacturers typically use 1,000, which is why a advertised drive shows less capacity once formatted.
