What is the difference between the temperature scales of Celsius/Centigrade (oC), Fahrenheit (oF) and Kelvin (oK) and how do I convert between these?
Kelvin & Celsius Celsius & Fahrenheit K = C + 273 C = 5/9 x (F – 32) C = (0.556 x F) – 32 C = K – 273 F = (9/5 x C) + 32 F = (1.8 x C) + 32 Fahrenheit – The Fahrenheit temperature scale is based upon 32 oF as the freezing point of water and 212 oF as the boiling point of water. (The Fahrenheit scale was devised by Gabriel Daniel Fahrenheit (1686-1736), a natural philosopher who invented the mercury thermometer in 1714.) Celsius (Centigrade) – The Celsius (Centigrade) temperature scale is based upon 0 oC as the freezing point of water and 100 oC as the boiling point of water. The formulas to convert between Fahrenheit and Celsius (Centigrade) come from the fact that there are 180 degrees (212-32) between freezing and boiling in the Fahrenheit temperature scale, so each degree in the Fahrenheit scale is equal to 100/180 (or 5/9) of the Celsius/Centigrade scale. (The Celsius scale was devised in 1742 by Anders Celsius (1701-1744), a Swedish professor of astronomy.) Kelvin – The Kelvin tem
