2-2 TEMPERATURE

Fahrenheit and Celsius Gabriel Fahrenheit (1686-1736) was

one of the first to develop a thermometer. His standards were quite arbitrary.

Scientists eventually went with Anders Celsius (1701-1744) system because it fit the metric system better.

William Thomson, Lord Kelvin (1824-1907) developed a system that is the SI standard today based on Absolute Zero.

This is the point where ALL molecular motion STOPS completely.

THIS IS A THEORETICAL MEASURE

Conversion. oC =5/9 x (oF - 32)

Conversion. oF = 9/5oC + 32

SI unit Kelvin (K) contains absolute zero. (-273oC)

Conversion. oC = K – 273

Conversion. K = oC + 273
