Temperature ConversionFormulae with BRACKETS and FRACTIONS Some Temperature FactsCelsius and Fahrenheit are the same at -40°Water boils at 100°C which is 212°FWater freezes at 0°C which is 32°FHuman body temperature is around 37°C which is 98.6°FWhich countries still use Fahrenheit?Fahrenheit is used in?the United States,?the Cayman Islands and Liberia.Older folk in the UK, Ireland and Canada will also use it. You can get Google on your smartphone to do the conversion.We are going to use formulae to convert from one to the other.Each formula is straightforward and good for some practise.Converting from Celsius to Fahrenheit where C is the temp in Celsiusand F is the temp in FahrenheitIn Algebra, the “x” for multiplication is often left out.If two terms are beside each other they mean multiply them.In this equation:means the same asThere is a fraction in the formula.When you multiply by a fraction, you divide by the bottom and times by the top. means the same asExampleCelsius into Fahrenheit where C is the temp in Celsiusand F is the temp in Fahrenheit What’s the temperature in Fahrenheit if it’s 28°C?You use the number 28 for C in the formula above (I’ve it in blue)Questions:Celsius into Fahrenheit where C is the temp in Celsiusand F is the temp in FahrenheitWhat’s the temperature in Fahrenheit if it is:Q1 15°C…………Q2 30°C…………Q3 7°C…………left558800ANSWERSQ1 59°FQ2 86°FQ3 44.6°F00ANSWERSQ1 59°FQ2 86°FQ3 44.6°FConverting from Fahrenheit to CelsiusHere’s the formula for converting the other way, Fahrenheit to Celsius where C is the temp in Celsiusand F is the temp in FahrenheitRemember to do anything in a bracket firstExample: What’s the temperature in Celsius if it’s 82°F?You use the number 82 for F in the formula above (I’ve it in blue)Remember to do anything in a bracket firstQuestions:Fahrenheit into Celsius where C is the temp in Celsiusand F is the temp in Fahrenheit Q4. 110°F…………Q5. 90°F…………Q6. 60°F…………Q7. 50°F…………Q8.
