room temperature
B2Neutral to formal
Definition
Meaning
The average ambient temperature of a room, typically considered comfortable for humans, generally between 20°C (68°F) and 22°C (72°F).
A serving condition for food and drink (especially wine) where it is neither chilled nor heated; also, a state of mild, moderate, or unexceptional condition (e.g., "room-temperature intelligence").
Linguistics
Semantic Notes
In scientific/technical contexts, it is often defined as 20–25°C (68–77°F). In British culinary context, "room temperature" for wine or butter means noticeably cooler than typical American room heating.
Dialectal Variation
British vs American Usage
Differences
British homes are often cooler in winter, so 'room temperature' may be perceived as lower (e.g., 18°C). In the US, due to higher central heating settings, it is often perceived as warmer (e.g., 22–24°C).
Connotations
In UK wine tasting, 'room temperature' means around 18°C (coolish), whereas in casual US usage it can mean warmer. 'Room-temperature' as a modifier (e.g., 'room-temperature coffee') is neutral-negative in both.
Frequency
More frequent in British English in culinary/wine contexts; equally common in scientific/technical English in both varieties.
