What temperature in Celsius is considered cold?

In common usage, cold is often a subjective perception. A lower bound to temperature is absolute zero, defined as 0.00 K on the Kelvin scale, an absolute thermodynamic temperature scale. This corresponds to −273.15 °C on the Celsius scale, −459.67 °F on the Fahrenheit scale, and 0.00 °R on the Rankine scale.


Is 84 degrees Fahrenheit hot?

84 Fahrenheit is considered a warm temperature by most people’s standards. A pleasant temperature would be 70 to 73 degrees F, and a cold temperature would be 60 degrees and below.
