The Rankine scale is an absolute scale of thermodynamic temperature. It was proposed by the physicist Macquorn Rankine in 1859. Similar to the Kelvin scale, which was first proposed in 1848,[1] zero on the Rankine scale is absolute zero, but a temperature difference of one Rankine degree (symbol: °R) is defined as equal to one Fahrenheit degree, rather than the Celsius degree used on the Kelvin scale. A temperature of 0 K (−273.15 °C; −459.67 °F) is equal to 0 °R.
The degree Celsius (symbol: °C) is a unit of temperature on the Celsius scale. Originally this scale was known as the centigrade scale. Even now many people refer degree Celsius as centigrade. The Celsius scale is named after Swedish astronomer Anders Celsius. He developed a similar temperature scale in 1742. Celsius is most widely used temperature scale in the world.
On this Celsius scale, 0 °C temperature represents the freezing point of water and 100 °C represents the boiling point of water at 1 atm pressure.
