Gram-Force
Gram-force (gf) is a unit of force defined as the force exerted by one gram of mass in standard gravity, approximately equal to 0.00980665 newtons.
History/Origin
The gram-force originated in the late 19th and early 20th centuries as part of the centimeter-gram-second (CGS) system of units, used to express forces in terms of grams and centimeters. It was commonly used in physics and engineering before the adoption of the SI system.
Current Use
Gram-force is now largely obsolete and replaced by the SI unit newton (N) in scientific and technical contexts. However, it may still be used in some engineering fields, calibration, and for illustrative purposes in educational settings.
Attonewton
An attonewton (aN) is a unit of force equal to 10^-18 newtons.
History/Origin
The attonewton is part of the SI prefixes system, introduced to measure extremely small forces, with its usage becoming more relevant in nanotechnology and precision measurements.
Current Use
Attonewtons are used in scientific research involving microscopic forces, such as in atomic and molecular physics, and in nanotechnology applications where very small forces are measured.
