Frequently asked questions
How is temperature converted?
Temperature uses proper formulas (not simple ratios) — Celsius, Fahrenheit and Kelvin convert through an absolute base so values like 0°C → 32°F are exact.
Does data use 1024 or 1000?
The digital storage category uses binary units (1 KB = 1024 bytes), matching how operating systems typically report file sizes.
Why does the result show rounding?
Results are shown to a set number of significant digits to stay readable. Increase the precision if you need more decimal places.
Is anything uploaded?
No. All conversions are computed locally in your browser.
