How it works
We use deg F = (deg C x 9/5) + 32.
Exact relationship: deg F = (deg C x 9/5) + 32
Example: 0 deg C = 32.000 deg F.
Notes: Results are rounded in the default view.
Examples
- 0 deg C = 32.000 deg F
- 20 deg C = 68.000 deg F
- 100 deg C = 212.000 deg F
FAQ
What physical quantity do degrees Celsius and degrees Fahrenheit express?
Degrees Celsius express temperature on a metric-friendly scale used heavily in science, engineering, and international technical work. Degrees Fahrenheit express temperature, meaning thermal state rather than size, speed, or mass.
What is the difference between degrees Celsius and degrees Fahrenheit?
Degrees Celsius and degrees Fahrenheit both express temperature, but their zero points and scaling conventions differ, so temperature conversions often require both multiplication and an offset.
What is the history of the degree Celsius?
The Celsius scale was developed from the centigrade system and became the dominant everyday and technical temperature scale in most of the world.
What is the history of the degree Fahrenheit?
The Fahrenheit scale was developed in the early eighteenth century and remains common in U.S. weather, HVAC, and consumer temperature contexts.
Were the degree Celsius and degree Fahrenheit discovered by a specific person?
Celsius was created as a defined scale associated with Anders Celsius and later standardized, not discovered as a natural object. Fahrenheit was created as a temperature scale by Daniel Gabriel Fahrenheit rather than discovered as a natural object.
Where are degrees Celsius and degrees Fahrenheit used in science and engineering?
Degrees Celsius are used in laboratories, industrial processes, environmental control, standards documents, and international engineering communication. Degrees Fahrenheit are common in U.S. building systems, cooking, weather reporting, process equipment, and consumer product interfaces.
Why are temperature conversions different from simple unit ratios?
Temperature scales can have different zero points, so many conversions need both a scale factor and an offset rather than a single multiplication constant.
Can I trust this for critical calculations?
Use this for convenience and verify against your governing standard, specification, or process requirement for critical work. Temperature interpretation often depends on context, instrumentation, and tolerance.
