The Kelvin scale (apex)
Absolute zero is the lowest number on the Kelvin scale. It can be converted to Celsius and Fahrenheit.
The idea is to start at absolute zero - the lowest possible temperature. This happens to be -273.16 on the Centigrade (Celsius) scale. The Kelvin scale has no negative temperatures; zero degrees Kelvin is the lowest possible temperature.
The Kelvin temperature scale is designed so that zero Kelvin is the lowest possible temperature, at which all molecular motion has ceased, hence, it is absolute zero.
Absolute temperature is the same as the Kelvin temperature scale. Zero degrees Kelvin is the lowest possible temperature, meaning that there is no heat at all. It is equal to minus 273 degrees Celsius.
The lowest possible temperature. On the Kelvin scale, this temperature is zero degrees; on the Celsius scale, about minus 273 degrees.

Absolute zero is the lowest number on the Kelvin scale. It can be converted to Celsius and Fahrenheit.
The lowest temperature (absolute zero) on the Celsius scale is -273.15°
The idea is to start at absolute zero - the lowest possible temperature. This happens to be -273.16 on the Centigrade (Celsius) scale. The Kelvin scale has no negative temperatures; zero degrees Kelvin is the lowest possible temperature.
The lowest possible temperature on the Celsius scale is -273.15 °C. This is the same as 0 K on the Kelvin scale, which is the SI base unit of thermodynamic temperature. This temperature is called absolute zero, because it is the point where all molecular motion stops.
Kelvin temperature scale uses absolute zero as the zero. Though you can find absolute zero in all temperature scales i.e. −459.67 degrees Fahrenheit and -273.15 degrees Celsius. But Kelvin is the scale that absolute zero is 0.
The lowest point on any temperature scale, the temperature at which all (non-quantum mechanical) motion ceases; hence absolute zero occurs at the zero in the Kelvin scale, -273 degrees on the centigrade (Celsius) scale and -459.7 degrees on the Fahrenheit scale.
Yes, it is always positive. 0 K is the lowest temperature there can be.
The Kelvin temperature scale is designed so that zero Kelvin is the lowest possible temperature, at which all molecular motion has ceased, hence, it is absolute zero.
