The Kelvin scale starts at absolute zero
The Kelvin scale starts at absolute zero, the coldest possible temperature, making scientific calculations precise by eliminating negative values and directly relating temperature to molecular energy.
The Kelvin scale begins at absolute zero, the universe's coldest possible point, equivalent to -273.15 degrees Celsius. This unique scale, proposed by Lord Kelvin in 1848, avoids negative numbers, making scientific calculations much simpler and more accurate. For instance, water freezes at 273.15 Kelvin and boils at 373.15 Kelvin.
