You may need to convert a temperature in Celsius to Fahrenheit. The Celsius scale is the SI temperature scale, while the Fahrenheit scale is how Americans and people from some other countries measure temperature. This example problem shows the steps necessary to convert Celsius temperatures to the Fahrenheit scale.
Celsius to Fahrenheit Example
Dry ice, or frozen carbon dioxide sublimes (phase change between solid to gas) at -78.5 °C under normal atmospheric pressures. What is this temperature in Fahrenheit?
Solution:
The formula needed to convert Celsius to Fahrenheit is:
°F = 9⁄5°C + 32 = 1.8 °C + 32
where °F and °C are the temperatures in Fahrenheit and Celsius respectively.
To solve this, plug the Celsius temperature, -78.5 °C into the formula.
°F = 1.8(-78.5) + 32
°F = -141.3 + 32
°F = -109.3 °F
Answer:
Dry ice sublimes at -109.3 °F under normal atmospheric pressure.
