How to convert temperature in degree celcius and fahrenheit to kelvins .

Becky is going to take her dog for walk in the park, but before she leaves, she watches the weather report. According to the weather report, it is 81.0 outside. What is the outside temperature in kelvins?

ok, you did not mention weather the outside temp 81.0 outside is in Fahrenheit or degree celcius...but i will tell you the conversion of both

K = 0C  + 273 = 81.0 + 273 = ? K

if it is in Fahrenheit then first convert it to degree celcius and then to Kelvins :

0C = F - 32 / 1.8

then use K = 0C  + 273 to convert it to Kelvin
