tepid

adj. warm, lukewarm

Fahrenheit is a temperature scale named after the German-Dutch physicist Daniel Gabriel Fahrenheit (1686–1736), who proposed it in 1724.In this scale, the melting point of water is 32 degrees Fahrenheit (written “32 °F”), and the boiling point is 212 degrees, placing the boiling and melting points of water exactly 180 degrees apart. On the Celsius scale, the melting and boiling points of water are exactly 100 degrees apart, thus the unit of this scale, a degree Fahrenheit, is of a degree Celsius. The Fahrenheit scale coincides with the Celsius scale at -40 °F, which is the same temperature as -40 °C.
