Room temperature is 17 K lower than human body temperature. Selected basis: approximate values.
Celsius and Fahrenheit zero points are offsets. Compare temperature differences, not ratios in °C or °F. The kelvin axis starts at absolute zero.
20 °C - Temperature; defined reference.
Room temperature describes indoor air conditions generally considered comfortable for people and suitable for ordinary activities.
