![]() The Fahrenheit equivalent is the Rankine temperature scale. One can convert degrees Celsius to kelvins by adding 273.15 thus, the boiling point of water, 100C, is 373.15 K. The only difference between the scales is their starting points: 0 K is "absolute zero," while 0C is the freezing point of water. Kelvin Scaleĭegrees Celsius (C) and kelvins (K) have the same magnitude. Celsius is officially used in the international system of units. That is to say that water freezes at 0 and boils at 100. It scales 100 degrees (making it "centigrade") between the freezing point of water and the boiling point of water at sea level. But, we get odd numbers like water freezing at 32 degrees and boiling at 212 degrees, humans running at about 98 degrees, and room temperature being around 70 degrees.Īstronomer AndersCelsius made a system that's a bit more scientifically focused. These are touchstones that one might find in nature, so it makes a degree of sense. ![]() Physicist Daniel Gabriel Fahrenheit, who created the scale a couple hundred years ago, allegedly graded temperature from the freezing point of brine (water, salt, and ice) to around the average human body temperature. ![]() Simply take 30 off the Fahrenheit value, and then half that number. There's a simple rule to convert Fahrenheit to Celsius that should be good enough for general use. So how did we come up with the degrees Fahrenheit and degrees Celsius? Those have different answers, in that the Fahrenheit numbers are a bit off-kilter. Quick and easy Fahrenheit to Celsius conversion. ![]()
