Answer:
It is kelvin, not Celsius as most think.
The kelvin (symbol: K) is a measure of temperature now typically used in science and industry. One kelvin equals an increment on the thermodynamic temperature scale of 1/273.16 degrees Celsius or one degree Fahrenheit: “0 K” marks absolute zero, the hypothetical temperature at which all molecular motion stops and matter becomes inert (a form of death).
The temperature unit that we use today originated from a Swedish astronomer called Anders Celsius who created it to simplify exactly what he had already done for his ‘centigrade’ units three years earlier. After successfully inventing this new scales, he then took into account the other half of his findings by taking the other hundredth of the original thermometer scale to create a unit called ‘centigrade’. This was actually invented to measure temperature or even climate by using two scales; -50 degrees Celsius to 50 degrees Celsius.
Answer:
SI unit of temperature is degrees Celsius, or more commonly Celsius or degrees Centigrade. Degrees Fahrenheit is a less common but still in use measurement that SI units convert to by multiplying by 1.8 and add 32 (4 × 1.8 + 32 = 37). A less common measure of temperature outside the SI system is kelvin, which also only has two units; Kelvin and degrees Kelvin [1].
