It has the reference points being the freezing points of water 0 В°Re and boiling point of water being 80 В°Re. RГ©aumur scales was introduced by RГ©ne de RГ©aumur in 1730. So the freezing point of water equals 491.67 В°Ra. One Rankine degree is the same size as one Fahrenheit degree. The reference point of Rankine scale is absolute zero point being 0 В°Ra, like in Kelvin scale. Rankine scale was presented by a Scottish William Rankine in 1859. The temperature of the human body is about 98 вЏ on the revised scale.

Nowadays the Fahrenheit scale is redefined in a way that the melting point of ice is exactly 32 вЏ and the boiling point of water exactly 212 вЏ. The two main reference points of the scale are the freezing point of water being specified as 32вЏ and the temperature of human body being 96вЏ. The two main reference points of the Celsius scale were the freezing point of water (or melting point of ice) being defined as 0 вЊ and the boiling point of water being 100 вЊ.ДЇahrenheit scale was first introduced by a Dutch Gabriel Fahrenheit in 1724. The unit and the actual Celsius scale was first presented by a Swede Anders Celsius in 1742. Kelvin is currently defined as the fraction 1/273.16 of the thermodynamic temperature of the triple point of water, absolute zero point being 0 K.Д¬elsius is currently a derived unit for temperature in the SI system, Kelvin being the base unit. Kelvin unit was first presented by William Thomson (Lord Kelvin) in 1848. Kelvin unitвЂ™s abbreviation is K (no degree or degree sign).

Kelvin is the base unit of temperature in the SI system (International System of Units). CELSIUS TO FAHRENHEIT CONVERSION CHART This chart is a quick converter to help you change temperatures in Celsius (вЊ), or Centigrade, to Fahrenheit (вЏ) from -30вЊ to 104вЊ (or -22вЏ to 219.2вЏ). The temperature of an object can be defined by the average kinetic energy of its atoms and molecules. All materials have atoms and molecules that are constantly moving, vibrating or rotating. Temperature is an intensive quantity and describes the energy state of the matter.
