Knowing how to convert Celsius to Fahrenheit is useful when converting temperature measurements from different countries. Americans, people from U.S. territories, and some Caribbean countries report temperatures in Fahrenheit. Most of the world uses the Celsius scale. Fortunately, the temperature conversion is simple. Here is the formula with examples of how to convert Celsius to Fahrenheit.
- Multiply the Celsius temperature by 1.8
- Add 32.
Formula to Convert Celsius to Fahrenheit
Choose either of two formulas to convert Celsius to Fahrenheit. One uses a fraction, while the other uses its decimal equivalent.
The formula to convert Celsius to Fahrenheit is
°F = 9⁄5°C + 32
where °F and °C are the temperatures in Fahrenheit and Celsius respectively.
Avoid the fraction and use 1.8 in place of 9⁄5.
°F = 1.8 °C + 32
Convert Celsius to Fahrenheit Example
Question: Room temperature is 25 °C. What is 25 °C in °F?
Solution: Use the formula:
°F = 1.8 °C + 32
Plug in 25 into the °C part of the equation.
°F = (1.8 x 25) + 32
°F = 45 + 32
°F = 77 °F
Answer: 25 °C is the same as 77 °F.
Convert Body Temperature From Celsius to Fahrenheit
Body temperature is 37 °C. What is this temperature in Fahrenheit?
°F = 1.8 °C + 32
°F = (1.8 x 37) + 32
°F = 66.6 + 32
°F = 98.6
