Not outside, and not with things I happen to have around the house,
but it's easy to produce in a properly equipped laboratory.
285 K?
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
273.16 deg K = 0.01 deg C
K = 273.15 + C K = 273.15 + -25 K = 248.15
25 kilometres = 15.5 miles

248.15 K
In the morning it was about 47 K, and to 8 AM. it was overcast. Then the heaven cleared, and on 2 PM. temperature reached 65 K. In the evening it overcasted again and the temperature was about 45 K.
The conversion formula is: K = (C + 273.15)K = 25 + 273.15Kelvin = 298.15
25 degrees Celsius = 298.15 kelvin[K] = [°C] + 273.15
If we assume "room temperature" to be 25 °C (77 °F) then that would equate to 298.15 K. Different areas assume different standard "room temperature" - but it usually falls between 20 °C (293.15 K) and 30 °C (303.15 K)
add 273 to get from C to K 25 + 273 = 298 Kelvins
To convert Celsius to Kelvin, add 273. So, the Kelvin temperature of 25 degrees Celsius is 298 Kelvin (25 + 273 = 298).
The accepted standard state values for temperature is 298 K (25°C) and pressure is 1 bar (100 kPa).
The average surface temperature is 72 K.
Room temperature is commonly considered to be around 20-25 degrees Celsius. To convert 23 degrees Celsius to Kelvin, you simply add 273.15 to get 296.15 Kelvin, which is approximately equivalent to room temperature.
