The theoretically lowest temperature in the Celsius scale is -273.15, called absolute zero temperature that describes the ultimately minimum point of atomic thermal motion. As a unit, Celsius degree °C is equal to the Kelvin degree °K, although their scales are different, since °K maps 0 to the absolute zero.
At the time of taking this screen shot you can see that my processor's cores are running at an average of about ~45-degrees Celsius. And, since Core Temp also shows me what the processor's load is, I can tell that these temperature readings are coming from when the CPU is idling (the screenshot shows that my CPU is at a 0% load, …

What is gypsum what will happen if it is heated at 100 degree Celsius? When gypsum is heated to a temperature of 100⁰C (373K), it loses three-fourths of its water of crystallisation and forms plaster of Paris (CaSO4. Why is gypsum not heated over 100 degree Celsius? Gypsum should not be heated in more than 100 degree Celsius.
Take the metric unit of temperature and apply the following formula: (C * 9/5) + 32 = F where we use C for degrees Celsius and F for degrees Fahrenheit. If you wish to do a temperature unit conversion from F to C you need to reverse the formula. The result should look like this : (F-32) * 5/9 = C.
