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.
Poundalpd
Target UnitThe poundal (symbol: pd) is a unit of force that is part of the foot-pound-second (FPS) system of measurements. It is defined as the force required to accelerate a one-pound mass by one foot per second squared. This unit is derived from the fundamental physical principles of mass, length, and time, making it a distinct measure of force that is primarily used in certain engineering and physics contexts. The poundal is less commonly used than the Newton, the SI unit of force, but remains significant in certain fields, particularly in the United States, where the FPS system is still in use. The poundal helps bridge the gap between traditional and modern measurements, providing a unique perspective on force in mechanical contexts.
Current Use
The poundal is primarily utilized in specific engineering disciplines and contexts, particularly in the United States, where the foot-pound-second system is still relevant. It is often found in applications involving mechanical systems, structural engineering, and fluid dynamics. For example, engineers may use poundals to calculate forces acting on components in machinery or to assess stresses in materials. Despite the global shift towards the SI system and the widespread adoption of the Newton, the poundal remains in use among certain practitioners who prefer the FPS system for specific calculations, particularly in fields with historical ties to imperial units. Its usage is particularly notable in educational settings where traditional units are taught alongside modern metrics, allowing students to appreciate the historical context of measurement systems.
Fun Fact
The poundal was introduced by Lord Kelvin, a prominent figure in thermodynamics.

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.

Poundal
force • Non-SI
Definition
The poundal (symbol: pd) is a unit of force that is part of the foot-pound-second (FPS) system of measurements. It is defined as the force required to accelerate a one-pound mass by one foot per second squared. This unit is derived from the fundamental physical principles of mass, length, and time, making it a distinct measure of force that is primarily used in certain engineering and physics contexts. The poundal is less commonly used than the Newton, the SI unit of force, but remains significant in certain fields, particularly in the United States, where the FPS system is still in use. The poundal helps bridge the gap between traditional and modern measurements, providing a unique perspective on force in mechanical contexts.
History & Origin
The poundal was introduced in the late 19th century as part of the effort to provide a coherent unit of force within the foot-pound-second system of units. It was proposed by the engineer and physicist William Thomson, Lord Kelvin, who sought to create a practical system that would replace the less consistent measurements in use at the time. The introduction of the poundal aimed to standardize measurements of force in engineering and physics, particularly in the United States, where the FPS system was prevalent. The poundal's creation was a response to the growing need for reliable and consistent units of measure among scientists and engineers.
Etymology: The term 'poundal' is a portmanteau comprising 'pound,' referring to the unit of weight, and 'al,' which signifies a diminutive or a related unit. This combination indicates that the poundal is a force derived from the pound, highlighting the relationship between mass and force in the FPS system.
Current Use
The poundal is primarily utilized in specific engineering disciplines and contexts, particularly in the United States, where the foot-pound-second system is still relevant. It is often found in applications involving mechanical systems, structural engineering, and fluid dynamics. For example, engineers may use poundals to calculate forces acting on components in machinery or to assess stresses in materials.
