Acar motor oil was measured and described using kelvin. which characteristic of matter was measured

Kelvin is a unit for temperature. The temperature of the car motor oil must have been measured and described. At 0 degree Celsius or freezing point of water, there is 273 Kelvin. At the boiling point of water, it reads 373 Kelvin. This is the standard used by scientists in solving in equations. However, Celsius and Fahrenheit are common to daily basis. 

They are like other investigations? say there was a murder u have to do blood test and finger prints which run through a lab.
