zeptosecond Under the International System of Units (via the International Committee for Weights and Measures, or CIPM), since 1967 the second has been defined as the duration of \\num{9,192,631,770} periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the caesium 133 atom.In 1997 CIPM added that the periods would be defined for a caesium atom at rest, and approaching the theoretical temperature of absolute zero, and in 1999, it included corrections from ambient radiation.

zeptowatt A power unit which is equal to the power used when work is done at the rate of 1 joule per second SI Derived https://en.wikipedia.org/wiki/Watt
zettaampere The ampere, often shortened to 'amp', is the SI unit of electric current and is one of the seven SI base units. SI Coherent Derived https://en.wikipedia.org/wiki/Ampere
zettacandela Candela is a unit for 'Luminous Intensity' expressed as 'cd'. The candela is the SI base unit of luminous intensity; that is, power emitted by a light source in a particular direction, weighted by the luminosity function (a standardized model of the sensitivity of the human eye to different wavelengths, also known as the luminous efficiency function). A common candle emits light with a luminous intensity of roughly one candela. SI Coherent Derived https://en.wikipedia.org/wiki/Candela
zettagram The kilogram or kilogramme (SI symbol: kg), also known as the kilo, is the base unit of mass in the International System of Units and is defined as being equal to the mass of the International Prototype Kilogram (IPK), which is almost exactly equal to the mass of one liter of water.

zettajoule The joule, is a derived unit of energy in the International System of Units. It is equal to the energy transferred to (or work done on) an object when a force of one newton acts on that object in the direction of its motion through a distance of one metre. SI Coherent Derived https://en.wikipedia.org/wiki/Joule
zettakelvin The kelvin, symbol K, is the primary unit of temperature in the International System of Units (SI), used alongside its prefixed forms and the degree Celsius. It is named after the Belfast-born and University of Glasgow-based engineer and physicist William Thomson, 1st Baron Kelvin (1824–1907). The Kelvin scale is an absolute thermodynamic temperature scale, meaning it uses absolute zero as its zero point. SI Coherent Derived https://en.wikipedia.org/wiki/Kelvin
zettameter SI prefixed variant of the SI base unit of meter SI Coherent Derived https://en.wikipedia.org/wiki/Metre
zettamole Adopted as part of the SI system in 1971, is that one mole of a substance contains just as many elementary entities (atoms, molecules, ions, or other kinds of particles) as there are atoms in 12 grams of carbon-12 (carbon-12 is the most common atomic form of carbon, consisting of atoms having 6 protons and 6 neutrons). This corresponds to a value of 6.02214179(30)x10^23 elementary entities of the substance. It is one of the base units in the International System of Units, and has the unit symbol (mol) SI Coherent Derived https://physics.nist.gov/cuu/Units/current.html
