Cold refers to the condition or subjective perception of having low temperature, the opposite of hot.[note 1] A lower bound to temperature is the absolute zero, defined as 0 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 °R on the Rankine scale. Wikipedia: Cold
