Question

"it was so cold yesterday that the temperature only reached 275." which temperature scale is being used? what would be the corresponding temperature on the other two scales?

Answer 1

Remembering back to science I believe that temperature is on the Kelvin scale. The corresponding temperature on the Celsius scale would be very close to zero degrees which is the freezing point. The corresponding temperature on the Fahrenheit scale would be 32 degree which again is the freezing point.

Answer 2

Answer is: Kelvin.
1) The temperature in degrees Celsius (°C) is equal to the temperature in Kelvin (K) minus 273,15.
T(°C) = T(K) - 273.15 = 275 - 273,15 = 1,85°C.
2) The temperature in degrees Fahrenheit (°F) is equal to the temperature in Kelvin (K) times 9/5, minus 459.67:
T(°F) = T(K) · 9/5 - 459,67 = 275 · 1,8 - 459,67 = 35,33°F.
