•Scientists use the Kelvin scale, which is based on the Celsius
scale, but has no negative numbers. Zero on the Kelvin scale is considered to be absolute zero;

•To convert a temperature reading into degrees Kelvin, simply
add 273.16 to the Celsius temperature.
•The absolute zero version of the Fahrenheit scale is the Rankine
scale. Add 460 degrees to Fahrenheit temperatures to obtain the Rankine
