Rankine to Reaumur Converter

Rankine

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.

Reaumur

The Réaumur scale (symbol: °Re or °r), also known as the 'octogesimal division', is a temperature scale for which the melting and boiling points of water are defined as 0 and 80 degrees respectively. The scale is named for René Antoine Ferchault de Réaumur, who first proposed a similar scale in 1730.
