Question

Convert 421.9 Kelvin to Celsius and then to Fahrenheit by using (degrees Celsius x 9/5) + 32 = degrees Fahrenheit.

Answer 1

300.02°F

Step-by-step explanation:

To convert 421.9.9 Kelvin to Celsius subtract 273 from 421.9 Kelvin

421.9-273=148.9°C

To convert 148.9°C to °F use the formula (°C x 9/5) +32

That is:

(148.9°C x 9/5) + 32

=300.02°C
