Thermometer with Celsius and Fahrenheit (Ged Carroll)
Discussing the weather with Americans often includes the need to convert Celsius to Fahrenheit temperature scales. Friends in Europe complain of heat when the temperature is 35° and my first thought is 35° is a pretty cold day. 35 °F is barely above the freezing point of water. I also know 35 °C is the same as 95 °F. I have to do that conversion to agree with my friend’s opinion of a hot day. Fortunately, it is easy to convert Celsius to Fahrenheit.
Convert Celsius to Fahrenheit Formula
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.
For those who don’t like working with fractions, use 1.8 in place of 9⁄5.
°F = 1.8 °C + 32
Convert Celsius to Fahrenheit Example
Question: Room temperature is often given a value of 25 °C in homework problems. What is 25 °C in °F?
Solution: Use the formula above
°F = 1.8 °C + 32
Plug in 25 into the °C part of the equation.
°F = 1.8 (25) + 32
°F = 45 + 32
°F = 77 °F
Answer: 25 °C is the same as 77 °F.
