FAQ
Are the currency rates live?
No. Currency uses fixed reference rates for rough estimates so the tool stays fully offline — check a bank for exact rates.
Does temperature conversion handle offsets?
Yes. Celsius, Fahrenheit and Kelvin use proper offset formulas, not simple multiplication.
Are data units binary or decimal?
Binary, where 1 KB is 1024 bytes, matching how operating systems report file sizes.
