List of foundational units. Foundational units here means units that are not derived from other units (as is m/s metre per second), units that do not contain any prefixes (such as kilo or milli), and units that do not contain any exponents (as does m² square metre). Further units can be assembled from foundational units according to specific rules, such as those of the “Unified Code for Units of Measure”.
