fahrenheit, celsius, Kelvin

Question

Denver's average temperature is 86 degrees F. What is the temperature in Celsius? What is the temperature in Kelvin?

Answer 1

Hi CeeCee,

 

We can change Fahrenheit into Celsius by using the quation:

 

C = (F - 32)*(5/9)

 

so if F = 86, we get:

 

C = (86 - 32)*(5/9)

 

C = 54*(5/9)

 

C = 30 degrees

 

 

Now let's convert F to Kelvin.

 

The equation we'll use this time is:

 

K = (F + 459.67)*(5/9)

 

K = (86 + 459.67)*(5/9)

 

K = 545.67*(5/9)

 

K = 303.15 degrees

 

Let me know if that helps or if you have more questions.

 

Thank you,

Tyler

Answer 2

Convert to Celcius using C = (5/9)(F-32)

 

C = (5/9)(86-32) = 5×54/9 = 270/9 = 30

 

Thus on average, it is 30° C in Denver.

 

Now convert this to Kelvin using K = C+273.15

 

K=30+273.15=303.15

 

Thus on average, it is 303.15 K in Denver.

 

Note that the degree symbol ° is not used when giving the temperature in units of Kelvin because this is the base unit of temperature in the metric system.
