Frequently Asked Questions

It converts the input to Celsius first, then derives Fahrenheit, Kelvin and Rankine using standard formulas. Everything runs locally in your browser.

Kelvin and Rankine are absolute temperature scales. Their zero point represents absolute zero, so negative values are outside the supported physical range.

The zone bar uses Celsius-based reference bands: freezing and below, comfortable ambient temperatures, warm body-adjacent conditions, hot temperatures, and boiling-level extremes.
