Temperature FAQ
Common questions about converting temperature units.
What units are supported in the Temperature converter?
Unitly supports 3 distinct temperature units: Celsius (°C), Fahrenheit (°F), Kelvin (K).
How does Unitly ensure accurate temperature calculations?
All calculations are executed client-side using NIST-calibrated constants and IEEE-754 precision filters to eliminate floating-point artifacts.
Can I convert backwards or swap units?
Yes! Click the quick-swap button (⇄) or simply edit either the "From" or "To" field directly for instant bidirectional calculation.
