Unit Explanations
Dynedyn
Source UnitThe dyne is a unit of force commonly used in the centimeter-gram-second (CGS) system of units. It is defined as the force necessary to accelerate a mass of one gram (g) at a rate of one centimeter per second squared (cm/s²). Mathematically, this relationship can be expressed as 1 dyn = 1 g·cm/s². The dyne is a relatively small unit of force, as it is used primarily in scientific contexts where precise measurements in small scales are vital, such as in physics, materials science, and engineering. The dyne remains relevant in certain specialized fields despite the widespread adoption of the SI unit of force, the newton, in most applications.
Current Use
Currently, the dyne is primarily used in fields where the CGS system is still favored, such as in certain branches of physics, engineering, and materials science. Its applications are particularly prevalent in laboratories that focus on molecular dynamics, surface tension, and frictional studies, as the dyne allows for precise measurements of small forces. In biology, for instance, researchers may use the dyne to quantify forces acting at the cellular level, such as adhesion forces between cells or between cells and substrates. Furthermore, in engineering disciplines, particularly in fields dealing with micro-mechanical systems, the dyne provides a convenient scale for assessing forces in tiny components. Although the newton has largely supplanted it in many contexts, the dyne remains relevant in the specialized scientific communities that continue to rely on the CGS system.
Fun Fact
The dyne is significantly smaller than a newton, with 1 newton equaling 100,000 dynes.
FemtonewtonfN
Target UnitA femtonewton (fN) is a sub-unit of force in the International System of Units (SI) and represents one quadrillionth of a newton. The newton, the SI unit of force, is defined as the force required to accelerate a mass of one kilogram by one meter per second squared. Therefore, a femtonewton can be described as the force needed to accelerate a mass of 1 kg at a rate of 10^-15 m/s². This minuscule unit is particularly useful in fields where tiny forces are of interest, such as in molecular biology, nanotechnology, and materials science. In practical terms, a femtonewton is a force so small that it is typically encountered at the atomic or molecular level, highlighting the sensitivity required in modern scientific measurements.
Current Use
The femtonewton is primarily utilized in advanced scientific research, particularly in fields such as nanotechnology, molecular biology, and materials science. In nanotechnology, researchers use femtonewtons to measure the forces that act on nanoscale materials, which are critical for the development of nanomachines and devices. In molecular biology, femtonewtons are employed to understand the forces involved in protein folding, DNA interactions, and the binding forces between ligands and receptors. The ability to measure such minute forces is essential for advancing our understanding of biochemical processes and interactions. Countries leading in the application of femtonewtons include the United States, Germany, Japan, and South Korea, where cutting-edge research facilities and laboratories are equipped with high-precision instruments capable of detecting forces at this scale. The applications extend to medical devices, where understanding the forces at the cellular level can lead to innovations in drug delivery systems and cancer treatment.
Fun Fact
The femtonewton is so small that it can be compared to the weight of a single red blood cell, which exerts a force of approximately 5 femtonewtons.

Definition
The dyne is a unit of force commonly used in the centimeter-gram-second (CGS) system of units. It is defined as the force necessary to accelerate a mass of one gram (g) at a rate of one centimeter per second squared (cm/s²). Mathematically, this relationship can be expressed as 1 dyn = 1 g·cm/s². The dyne is a relatively small unit of force, as it is used primarily in scientific contexts where precise measurements in small scales are vital, such as in physics, materials science, and engineering. The dyne remains relevant in certain specialized fields despite the widespread adoption of the SI unit of force, the newton, in most applications.
History & Origin
The dyne originated in the late 19th century as part of the CGS system, which was developed to provide a coherent set of units for scientific measurement. The CGS system emerged from the need for a practical measurement framework that could accommodate the growing complexity of physical phenomena in laboratory settings. The dyne was established during a time when the metric system was evolving, and scientists sought consistency in their measuring units, especially in fields like mechanics and electricity. The dyne fostered a more accessible understanding of force by relating it to the fundamental properties of mass and acceleration.
Etymology: The term 'dyne' is derived from the Greek word 'dynamis', meaning 'power' or 'force'.
Current Use
Currently, the dyne is primarily used in fields where the CGS system is still favored, such as in certain branches of physics, engineering, and materials science. Its applications are particularly prevalent in laboratories that focus on molecular dynamics, surface tension, and frictional studies, as the dyne allows for precise measurements of small forces.

In practical terms, a femtonewton is a force so small that it is typically encountered at the atomic or molecular level, highlighting the sensitivity required in modern scientific measurements.
History & Origin
The concept of force has been integral to physics since the time of Sir Isaac Newton, who formulated the laws of motion in the 17th century. The newton, as a unit of force, was adopted in 1889 during the 1st General Conference on Weights and Measures (CGPM). As the need for measuring extremely small forces grew with advancements in technology, particularly in microscopic and nanoscale research, the femtonewton was introduced as a practical subunit of the newton. It enables precise force measurements in the realms of atomic and molecular physics, where forces are often on the order of piconewtons and femtonewtons, allowing scientists to quantify interactions at an extremely small scale.
Etymology: The term 'femtonewton' combines the prefix 'femto-', derived from the Danish word 'femten' meaning 'fifteen', signifying a factor of 10^-15, with 'newton', named after Sir Isaac Newton.
