Kelvin is a base SI unit used to measure which quantity?

Explanation:
Understanding SI base units is key here. Kelvin is the base SI unit for measuring thermodynamic temperature. It uses an absolute scale that starts at absolute zero—the lowest possible temperature where particles have no thermal energy. Because one Kelvin equals one degree Celsius in size, Kelvin is often used in scientific formulas, especially those involving energy and gas behavior, since it provides a true zero point. Other base units measure different quantities: length uses the meter, electric current uses the ampere, and amount of substance uses the mole.
