How to convert temperature
Enter the temperature, choose the starting scale, then choose the target scale. Temperature conversions use offsets, so Fahrenheit, Celsius, and Kelvin are handled with full formulas rather than simple multiplication.
Temperature uses base Kelvin: K = value x factor + offset, then the target scale removes its own offset.

deg C
Celsius
Celsius is the everyday metric temperature scale, with water freezing at 0 deg C and boiling at 100 deg C at standard pressure.
deg F
Fahrenheit
Fahrenheit is commonly used in the United States for weather, room temperature, cooking, and body-temperature readings.
K
Kelvin
Kelvin is the SI thermodynamic temperature scale used in science, with 0 K representing absolute zero.

Formula model
Base-unit conversion
Temperature results are rounded for display, but the conversion constants keep enough precision for everyday scientific and weather use.
base = amount * factor + offset
result = (base - targetOffset) / targetFactor
result = (base - targetOffset) / targetFactor
FAQ
Temperature converter questions
Why is temperature different from other unit conversions?
Temperature scales do not all start at zero, so the converter applies an offset as well as a scale factor.
Can I convert below zero?
Yes. Negative Celsius and Fahrenheit values are valid, and Kelvin values convert normally as long as the input is physically meaningful.
