About this conversion
Intro
This page converts centigrade (°C) to fahrenheit (°F). Use it when your temperature is given in centigrade and you need the equivalent in fahrenheit for reports, engineering work, or everyday reference.
Definition
Temperature measures how hot or cold something is and is used in weather, cooking, manufacturing, HVAC, chemistry, and engineering. Quick context on fahrenheit: Fahrenheit (°F) is commonly used in the United States for weather, cooking, and daily temperature reporting. Water freezes at 32 °F and boils at 212 °F (at standard atmospheric pressure).
Formula: Centigrade to Fahrenheit
°F = (°C × 9/5) + 32
Multiply by 9/5 and add 32 to convert Celsius to Fahrenheit.

FAQs
How do I convert Centigrade to Fahrenheit?
Use the formula shown above and enter your value in the converter. It will calculate the equivalent in Fahrenheit (°F) instantly.
What is Fahrenheit (°F) used for?
Fahrenheit (°F) is commonly used in the United States for weather, cooking, and daily temperature reporting. Water freezes at 32 °F and boils at 212 °F (at standard atmospheric pressure).
Why does temperature conversion use “+32” or “+459.67”?
Temperature scales can have different zero points. Fahrenheit and Rankine use offsets relative to Celsius/Kelvin, so conversions include an addition/subtraction step.
Is Centigrade the same as Celsius?
Yes. Centigrade is a historical/alternate name for the Celsius scale, and the numeric values are the same.
Which unit is absolute: Celsius/Fahrenheit or Rankine?
Rankine is an absolute scale (like Kelvin). Celsius and Fahrenheit are relative scales that don’t start at absolute zero.
Do these conversions depend on pressure (like boiling point)?
The unit conversion itself does not depend on pressure. However, physical phenomena like boiling/freezing points can change with pressure—this tool only converts units.
