Aug 29, 2021 · Examples of Derived Units. For example, the watt, hertz, and coulomb are derived units named for people. Their symbols are W, Hz, and C, respectively. Other examples of derived units include meters per second (m/s), cubic meters (m 3), and joule per kelvin (J/K).
Dec 4, 2019 · In chemistry, a derived unit is an SI unit of measurement derived as a product of one or more of the seven base units. For example, the SI unit of force is the derived unit newton (N): One newton is equal to 1 m·kg/s 2. Cite this Article. Helmenstine, Anne Marie, Ph.D. "Derived Unit Definition."

Chemistry primarily uses five of the base units: the mole for amount, the kilogram for mass, the meter for length, the second for time, and the kelvin for temperature. The degree Celsius (oC) is also commonly used for temperature. The numerical relationship between kelvins and degrees Celsius is as follows.
The International System of Units is a system of measurement based on the metric system. The acronym SI is commonly used to refer to this system and stands for the French term, Le Système International d'Unités. The SI was adopted by international agreement in 1960 and is composed of seven base units in Table 1.6.1.
1/1,000,000,000,000. 1 picometer (pm) = 10 -12 m. When working with small numbers, we use a negative exponent. So 0.1 meters is 1 × 10 -1 meters, 0.01 is 1 × 10 -2 and so forth. Table above gives examples of smaller units. Note the use of the leading zero (the zero to the left of the decimal point).
Measurements provide much of the information that informs the hypotheses, theories, and laws describing the behavior of matter and energy in both the macroscopic and microscopic domains of chemistry. Every measurement provides three kinds of information: the size or magnitude of the measurement (a number), a standard of comparison for the ...
