Poundal
pdl
Definition
The poundal is a unit of force in the foot-pound-second (FPS) system of units. It is defined as the force required to accelerate a mass of one pound at a rate of one foot per second squared. The poundal is equal to approximately 0.138 Newtons.
History/Origin
The poundal was introduced as part of the FPS (foot-pound-second) system of units in the 19th century. It was widely used in physics and engineering before the adoption of the MKS (meter-kilogram-second) system. The name comes from the combination of "pound" and "acceleration".
Current Use
Still used in some areas of physics and engineering, particularly in the United States. Common in some engineering applications where the FPS system is still used. Used in some scientific instruments and laboratory equipment that were designed using the FPS system.

Attonewton
aN
Definition
An attonewton equals 10^-18 Newtons and represents an extremely small force unit used in precision applications. This unit is employed for describing forces in laboratory settings, precision instruments, and micro-measurements.
History/Origin
The attonewton was established as part of the metric system's decimal prefix system. The prefix "atto" (meaning 10^-18) was adopted in 1964. This unit provides a convenient way to express forces in the quintillionths of Newtons range.
Current Use
Used in laboratory settings for measuring extremely small forces, particularly in chemistry and physics experiments. Common in precision instruments and micro-measurements. Used in some engineering applications where extremely small force measurements are required.
