• Pascal (unit)Related: The pascal’s expression reduces to the base units kilogram, metre, and second.

• National Institute of Standards and TechnologyBroader topic: NIST maintains U.S. realizations of these fundamental units.

• Metric prefixRelated: Prefixes attach directly to base-unit names and symbols.

• Precision measurementBroader topic: Their definitions anchor measurement scales across experimental disciplines.

• Gas constantRelated: The modern SI definition fixes R through exact values of k and NA.

• Physical constantRelated: Their modern definitions are tied to fixed values of specified constants.

• Klaus von KlitzingRelated: The exact value of the von Klitzing constant supports the modern realization of the kilogram and electrical units.

• Scalar (physics)Related: Scalar measurements use units such as the kilogram and kelvin.

• Ampère's force lawRelated: The ampere's historical definition made conductor force central to the system's electrical unit.

• CaesiumRelated: The second is defined by fixing the frequency of a caesium-133 transition.

• Day (time unit)Narrower topic: The second, not the day, is the SI base unit for time.

• Kilogram per cubic metreRelated: The kilogram and metre are the base units behind kg/m³.

• X unitNarrower topic: Modern length measurements trace to the meter rather than a calcite standard.

• Astronomical system of unitsCompared with: Unlike astronomical units, they are designed as universal standards across the sciences.

• Geometrized unit systemRelated: They provide the conventional starting units converted into geometrized form.

• Inverse secondNarrower topic: The second is an SI base unit, so its inverse provides a coherent derived unit.
