The weather forecaster predicts that today's high will be 70. Which temperature scale is being used? What would be the corresponding temperature on the other two scales?
This is Fahrenheit
Celsius = (F - 32) (5/9) = [70 - 32] (5/9) = [ 38](5/9) about 21.1° C
Kelvin = [ F - 32 ] (5/9) + 273.15 = [ 70 - 32] (5/9) + 273.15 = about 294.26° K
