Practice with Temperature Conversions!
Interpret the temperature conversion
shown in the gif. 
37ºC =             ºF
 -10ºC =           ºF
Convert -10ºC to F.
A formula to convert from Celsius to Fahrenheit is given.
ºF =             + 32
ºF = (             x 1.8) + 32
A formula to convert from Celsius to Fahrenheit is given.
To take 9/5 of a number,you can first take 1/5 of the number, or ÷ 5,and then multiply by 9.
ºF =           + 32
35ºC =         ºF 
Convert 35ºC to ºF.
ºF = (           x 9/5 ) + 32
A formula to convert from Fahrenheit to Celsius is shown.
Note: To take 5/9 of a 
number, you can multiply 
by 5, and then divide by 9.
Convert 50ºF to ºC.
ºC = (        ) x 5/9
ºC = (         ºF – 32) x 5/9
50ºF =          ºC
