Question: at what absolute temperature do the celsius and fahrenheit scales give the same numerical value?
Answer: The Celsius scale and the Fahrenheit scale coincides at -40°, which is the same for both. When it comes to converting Celsius degrees into Kelvins, the formula is even simpler. 0 degrees Celsius is equal to 273.15 Kelvins. The basic formula is °C + 273.15 = K.
