A rule to change from temperature measured in degrees Celsius (∘C^{\circ}\text{C}∘C) to degrees Fahrenheit (∘F^{\circ}\text{F}∘F) is:
Multiply the temperature in degrees Celsius by 1.8 then add 32
The temperature in London is 12∘C12^{\circ}\text{C}12∘C.
Work out the temperature, in London, in Fahrenheit (∘F^{\circ}\text{F}∘F)
The temperature in New York is 54∘F54^{\circ}\text{F}54∘F
Work out the temperature, in New York, in Celsius (∘C^{\circ}\text{C}∘C)
