Temperature Converter
Convert Celsius, Fahrenheit and Kelvin through a single Kelvin baseline.
01 / CONVERT TEMPERATURE
CONVERTED VALUE
100 °C = 212 °F
Kelvin baseline: 373.15 K
§
How it works
Values convert through a kelvin baseline. Celsius uses t/°C = T/K − 273.15, and Fahrenheit uses °F = °C × 9/5 + 32. These are exact definitional relationships.
Assumptions & limits
- Linear scale conversions; no physical measurement uncertainty is modelled.

FAQ
- What is absolute zero?
- 0 K = −273.15 °C = −459.67 °F — the lowest possible temperature, where the kelvin scale starts.
