Why not? Any combination of SI units is another SI unit. Whether it is the unit of something physical or has its own name is another question, but it is still in the realm of the system.CWatters said:In general you can't assume a combination of SI units automatically makes another SI unit.

SI units, or the International System of Units, are the globally recognized system of measurement units used in science, engineering, and everyday life. They were established in 1960 and are based on seven base units: meter (m), kilogram (kg), second (s), ampere (A), kelvin (K), mole (mol), and candela (cd).
SI units provide a universal language for measurements, ensuring consistency and accuracy in scientific experiments and calculations. They also allow for easy communication and understanding among scientists and researchers from different countries and disciplines.
Yes, SI units can be combined to form new units. This is known as a derived unit and is expressed as a combination of base units with mathematical operations. For example, the unit for speed, meters per second (m/s), is a derived unit as it is a combination of the base unit for distance (m) and time (s).
Yes, the combination of SI units to form derived units is still considered an SI unit. As long as the derived unit follows the rules and conventions of SI units, it is considered a valid measurement unit.
There are a few exceptions to the use of SI units, such as the use of non-SI units in certain fields, like aviation and marine navigation. Additionally, some non-SI units are still widely used in everyday life, such as inches, pounds, and gallons. However, these units can usually be converted to their equivalent SI units for scientific purposes.
