How cold is absolute zero?
There are three basic scales to measure temperature. They all share a couple of common points but one reaches much lower on the thermometer.

Science Trek
Science Trek is a place where parents, kids, and educators can watch short, educational videos on a variety of science topics. Every Monday Science Trek releases a new video that introduces children to math, science, technology, engineering, and math (STEM) career potentials in a fun, informative way.[MUSIC] Joan Cartan-Hansen, Host: There are three basic scales to measure temperature: Fahrenheit, Celsius, and Kelvin.
Fahrenheit and Celsius are tied to water.
On the Fahrenheit scale, water freezes at 32 degrees.
On the Celsius scale, water freezes at zero.
Water boils at 212 degrees on the Fahrenheit scale and at 100 degrees on the Celsius scale.
But scientists working at very cold temperatures needed something different.
It's called the Kelvin scale.
This starts with absolute zero.
Absolute zero is the coldest possible temperature and nothing in the universe actually gets this cold.
Though the average temperature in space is less than three degrees Kelvin.
So if you are trying to figure out what scale to use you have to know where you are.
In the U.S., use Fahrenheit; in the rest of the world, use Celsius And if you're really cold, use Kelvin.
