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, 100☌, is 373.15 K. The only difference between the scales is their starting points: 0 K is "absolute zero," while 0☌ is the freezing point of water. Kelvin Scaleĭegrees Celsius (☌) and kelvins (K) have the same magnitude. Celsius is officially used in the international system of units. ![]() ![]() To find it, multiply the Celsius by 9/5 and add 32 to the result. That is to say that water freezes at 0 and boils at 100. The temperature of 180 Celsius is 356 Fahrenheit. 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 Anders Celsius 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. As one degree Celsius is equal to one Kelvin, boiling point of water is equal to 273.15 + 100 373.15 Kelvin. ![]() Zero degrees Celsius is now defined as 273.15K. Since its definition, the Celsius scale has been redefined to peg it to Kelvin. 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. The other point at which Celsius was set 100 degrees Celsius was defined as the boiling point of water. Feel free to use a calculator if youre crunched for time, or if youd rather not do the math by hand. 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. Multiply the Celsius temperature by 1.8 to get started.
