1. Celsius and Fahrenheit Use this web site or follow the slide show

2. Celsius and Fahrenheit are two different scales for measuring temperature. To convert a temperature from one to the other you must memorize two formulas and be able to pick the correct formula. If you know degrees Fahrenheit, use this formula: °F – 32 = °C 1.8 If you know degrees Celsius, use this formula: 1.8 (°C) + 32 = °F

3. FAHRENHEIT TO CELSIUS Enter your known number for °F. Then solve. Example: Convert the boiling point of water from °F into °C: Solution: Water boils at 212 °F, so: 212°F – 32 = 100°C 1.8 212-32= 180. 180 ÷ 1.8 = 100.

4. Answer: The answer is 100°C is the boiling point of water on the Celsius scale

5. Fahrenheit into Celsius... Now try this using normal body temperature: Convert 98.6°F into °C. When you have the answer, go to the next slide...

6. Answer: 37°C.

7. For more practice: 1. Convert freezing point in Fahrenheit into Celsius (Freezing = 32°F). 2. Convert 104°F into °C. After you have the answers, go to the next slide.

8. Answers: 1. 0°C 2. 40°C (note: a body temperature of 104°F or 40°C is dangerously high as in infection and sepsis)

9. Celsius to Fahrenheit ... The “other” formula

10. Celsius to Fahrenheit If you know the °C, you can convert this into °F using this formula: 1.8 (°C) + 32 = °F Try using your answers above in degrees Celsius and use the formula to get back to the degrees Fahrenheit (ie – convert boiling point, normal body temperature, and freezing point in Celsius back into degrees Fahrenheit).

11. Additional practice: 1. Convert 38.6°C into °F 2. Convert 16°C into °F When you are done, go to the next slide to check your answers.

12. Answers: 1. Round 101.48 up to 101.5°F 2. 60.8°F If you have any questions please ask for help!

13. FYI Many units have charts hanging on the nursing unit to give you conversions from Fahrenheit to Celsius. If you Google you can find a site that will automatically convert for you! Here’s a web site to try:
