Wills recorded temperatures in °F (Fahrenheit) and also as °r (Réaumur). Towards the end of the expedition, the only thermometer that Wills had was graduated in °r (Réaumur).

°r (Réaumur)

This unit of temperature was proposed by the French entomologist René-Antoine Ferchault de Réaumur (1683-1757) in 1730. The freezing point of water of 0°r was equivalent to 0°C, but the boiling point of water was set to 80°r. This obsolete temperature scale was quite commonly used in continental Europe.

Temperature conversions

Fahrenheit to Celsius   °C = (°F - 32) / 1.8
Fahrenheit to Réaumur   °R = (°F - 32) / 2.25
Celsius to Fahrenheit   °F = °C × 1.8 + 32
Celsius to Réaumur   °R = °C × 0.8
Réaumur to Celsius   °C = °R × 1.25
Réaumur to Fahrenheit   °F = °R × 2.25 + 32
