Unit Explanations
NewtonN
Source UnitThe newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work in classical mechanics. It is defined as the amount of force required to accelerate a mass of one kilogram (1 kg) at a rate of one meter per second squared (1 m/s²). This relationship is mathematically expressed by Newton's second law of motion, F = ma, where 'F' represents force in newtons, 'm' is mass in kilograms, and 'a' is acceleration in meters per second squared. The newton is a derived unit in the International System of Units (SI), and it encompasses the measurement of both force and weight, providing a standard for scientific and engineering calculations.
Current Use
Today, the newton is widely used across various industries and scientific disciplines. In physics, it provides a standard measurement for force, enabling consistent calculations in mechanics. Engineering fields, particularly mechanical and civil engineering, utilize newtons for designing structures and systems that can withstand forces like tension, compression, and shear. The automotive industry uses newtons to evaluate forces acting on vehicles during crashes or performance tests. In the field of robotics, newtons help in the precise calculation of forces required for movement and manipulation. Countries that adhere to the International System of Units, particularly those in Europe, Asia, and many parts of Africa and South America, use the newton in scientific research, education, and industry. The newton is also utilized in aerospace for calculating thrust and lift forces, ensuring safety and efficiency in flight.
Fun Fact
The newton is equivalent to 0.225 pounds-force, illustrating the differences between metric and imperial systems.
AttonewtonaN
Target UnitThe attonewton (symbol: aN) is a unit of force in the International System of Units (SI) that represents one quintillionth (10^-18) of a newton. It is a measure of force, which is defined as mass times acceleration, where a newton is the force required to accelerate a one-kilogram mass by one meter per second squared. The attonewton is utilized in fields requiring precise measurements of force, such as in nanotechnology and molecular biology, where forces can be incredibly small, making traditional units like the newton impractical. The attonewton allows scientists to express and measure these minuscule forces with high precision.
Current Use
The attonewton is primarily used in fields such as nanotechnology, molecular biology, and precision engineering, where forces are encountered at extremely small scales. In nanotechnology, researchers use attonewtons to measure the forces between nanoparticles or the forces exerted by biological molecules, such as DNA or proteins, during interactions. In molecular biology, the attonewton is crucial for understanding the forces at play in molecular machines and cellular processes. Countries leading in the use of this unit include the United States, Germany, Japan, and China, where cutting-edge research in nanotechnology and biotechnology is prevalent. The attonewton is also utilized in academic research, helping to quantify forces in experimental setups and theoretical models, enhancing the understanding of fundamental scientific principles.
Fun Fact
The attonewton is used to measure forces that are a billion times smaller than a newton.

force • SI Unit
Definition
The newton (symbol: N) is the SI unit of force, named after Sir Isaac Newton in recognition of his work in classical mechanics. It is defined as the amount of force required to accelerate a mass of one kilogram (1 kg) at a rate of one meter per second squared (1 m/s²). This relationship is mathematically expressed by Newton's second law of motion, F = ma, where 'F' represents force in newtons, 'm' is mass in kilograms, and 'a' is acceleration in meters per second squared. The newton is a derived unit in the International System of Units (SI), and it encompasses the measurement of both force and weight, providing a standard for scientific and engineering calculations.
History & Origin
The newton was introduced as a unit of force in 1948 at the 9th General Conference on Weights and Measures (CGPM) as part of the International System of Units (SI). This was done to standardize measurements internationally and to honor Sir Isaac Newton's foundational contributions to physics. Newton's work laid the groundwork for classical mechanics, particularly his laws of motion which are crucial to understanding force and its applications in various fields. The adoption of the newton helped facilitate a universal language in scientific discourse, allowing for more accurate communication and collaboration across different disciplines.
Etymology: The term 'newton' is derived from the name of Sir Isaac Newton, the renowned English mathematician, physicist, and astronomer, who is widely recognized for formulating the laws of motion and universal gravitation.

Attonewton
force • Non-SI
Definition
The attonewton (symbol: aN) is a unit of force in the International System of Units (SI) that represents one quintillionth (10^-18) of a newton. It is a measure of force, which is defined as mass times acceleration, where a newton is the force required to accelerate a one-kilogram mass by one meter per second squared.

The attonewton allows scientists to express and measure these minuscule forces with high precision.
History & Origin
The concept of measuring small forces became increasingly relevant in the 20th century, especially with advancements in technology that allowed for the manipulation of particles at the nanoscale. The term 'attonewton' was formally introduced to provide a standardized way of quantifying these small forces, which are often encountered in experimental physics and engineering. The development of sensitive instruments, such as atomic force microscopes, further necessitated the need for precise force measurements at this scale. As scientific research expanded into the realms of nanotechnology and molecular interactions, the attonewton became a crucial part of the measurement vocabulary.
Etymology: The prefix 'atto-' originates from the Danish word 'atten,' meaning 'eighteen,' which denotes a factor of 10^-18. Combined with 'newton,' named after Sir Isaac Newton, who formulated the laws of motion and universal gravitation, the term denotes a force measurement that is 10^-18 of a newton.
