• heat

• thermometer

• Celsius / Fahrenheit

• temperature

To convert from Celsius to Kelvin, we must ---- to ℃

• add 273.15

• subtract 32

• add 5/9

• subtract 273.15

Which of the following formula is correct?

• 
  

  $\degree C=\frac{5}{9}F-32$
  

• $℉=\frac{9}{5}\left(℃+32\right)$

• $℃=\frac{5}{9}(℉–32)$

• $𝑲=\degree F+273.15$
