Which is not a derived SI unit?

Question

Quizplus · Accepted Answer

The derived SI units are units of measurement derived from the seven base units specified by the International System of Units (SI). They are made through combinations of base units to measure things like force, pressure, and energy. For example, Pascal (Pa) is a derived unit for pressure, Joule (J) is for energy, and Coulomb (C) is for electric charge. The second (s), however, is a base SI unit used to measure time, not a derived unit.
