Temperature Converter (°C, °F, K)
Convert between Celsius, Fahrenheit and Kelvin for furnace and thermal work. Type into any field and the other two follow immediately.
For reference: alumina melts near 2050 °C, cement clinker burns near 1450 °C, steel melts near 1538 °C.
Formulas used
- °F = (°C × 9 ÷ 5) + 32
- K = °C + 273.15
- °C = (°F − 32) × 5 ÷ 9
Practical notes
- Kelvin is the SI base unit of temperature; its zero is absolute zero, −273.15 °C.
- Temperature differences convert differently from temperatures: a difference of 1 °C equals 1 K but 1.8 °F.
Frequently asked questions
How do I convert Celsius to Fahrenheit?
Multiply by 9, divide by 5, then add 32. So 1000 °C is 1832 °F.
What is absolute zero in Celsius?
Absolute zero, 0 K, equals −273.15 °C.
