cgs system
Definition
- Noun:
- A system of measurement: The cgs system is a metric system of physical units based on the centimeter as the unit of length, the gram as the unit of mass, and the second as the unit of time.
Usage
- The cgs system is used primarily in scientific contexts, especially in physics and engineering, for expressing mechanical quantities. It is an alternative to the MKS (meter-kilogram-second) and SI (International System of Units) systems.
Examples
- Noun:
- In classical electromagnetism, many formulas were originally derived using the cgs system.
- The dyne, the unit of force in the cgs system, is defined as one gram centimeter per second squared.
Advanced Usage
- "cgs units": Refers to the specific units (e.g., dyne, erg, poise) defined within the cgs framework.
- Viscosity is often measured in poise, which is a unit in the cgs system.
Variants and Related Words
- CGS: A common abbreviation for the cgs system.
- Centimeter-gram-second system: The full name of the cgs system.
- MKS system: A related metric system based on the meter, kilogram, and second.
- SI system: The modern International System of Units, which is based on the MKS system.
Synonyms
- Centimeter-gram-second system: The full, formal name.
- Gaussian units: A system of units for electromagnetism based on the cgs system.
Notes
- While the cgs system is largely superseded by the SI system in most formal and international contexts, it is still used in certain subfields of physics (e.g., astrophysics, some areas of fluid dynamics) and can be found in older scientific literature.
Noun
-
system of measurement based on centimeters and grams and seconds
