- International System of Units : Metric unit system based on the metre, kilogram, second, ampere, kelvin, mole and candela.
- Speed of light : A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0 ≡ 299 792 458 m/s (exact).
- Metre (unit) : Unit of length; one of the seven SI base units.
- Second (physics) : Unit of time; one of the seven SI base units. }
- Electric constant : A physical constant in the International System of Units (SI) relating capacitance to area in classical vacuum with an exact value ε0 = 107/(4πc02) F/m, c0 being the defined value for the speed of light in classical vacuum in the SI units.
- Magnetic constant : A physical constant in the International System of Units (SI) relating mechanical force and electric current in classical vacuum with a defined value μ0 = 4π × 10−7 N/A2.
- Vacuum (partial) : A realizable vacuum with a gaseous pressure that is much less than atmospheric.
- Vacuum (quantum electrodynamic) : The term quantum electrodynamic vacuum, or QED vacuum, refers to the ground state of the electromagnetic field, which is subject to fluctuations about a dormant zero average-field condition.
