Frequently Asked Questions (FAQ)
Kelvin is an absolute scale where the unit itself ("kelvin") represents a fixed quantity, similar to meters or seconds — by international SI convention it's written as "300 K", not "300°K".
0 K (absolute zero) equals −273.15°C and −459.67°F — the point at which theoretically all atomic motion stops.
