If a thermometer indicates 40 degrees Celsius, what is the temperature in degrees Fahrenheit?

##104^circ##Fahrenheit

Just use this formula in converting Celsius to Fahrenheit:

°C to °F Multiply by ##9##, then divide by ##5##, then add ##32##

or ## (C^circ)9/5 +32##

##9/5 (40°C ) +32##

##rarr=360/5 +32##

##rarr72+32##

##rarr= 104 °F##

you may also use this given short cut way form :

##F^circ= 1.8 °C + 32##

##1.8 (40°C) +32##

##=72 +32##

##= 104 °F##

therefore using both equations arrived at the same answer which is

##104 °F##
