Derived unit of joule
WebJul 10, 2014 · 2 Answers Sorted by: 6 In SI, every base units and many derived units have an official name and an official symbol. For example "meter"-"m", "second"-"s" or "joule"-"J". There are grammatical rules how to use them, but more or less they are interchangeable. WebThe joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889). Sample conversions: joules joules to gallon [UK] of kerosene type jet fuel joules to inch ounce joules to wattsecond

SI derived units are units of measurement derived from the seven base units specified by the International System of Units (SI). They can be expressed as a product (or ratio) of one or more of the base units, possibly scaled by an appropriate power of exponentiation (see: Buckingham π theorem). Some are dimensionless, as when the units cancel out in ratios of like quantities. The SI has special names for 22 of these derived units (for example, hertz, the SI unit of measur… WebApr 9, 2024 · joule ( plural joules ) In the International System of Units, the derived unit of energy, work and heat; the work required to exert a force of one newton for a distance of …
