What is a Newton?
The newton (symbol: N) is the SI derived unit of force. It is defined as the force required to accelerate a mass of one kilogram at a rate of one meter per second squared (1 N = 1 kg⋅m/s²). This definition connects the newton to the fundamental SI units of mass, length, and time.
The newton is named after Sir Isaac Newton in recognition of his work on classical mechanics, particularly Newton's second law of motion. Our newton conversion tool helps you easily convert between newtons and other units of force. For example, 1 newton equals approximately 0.2248 pound-force or 0.1020 kilogram-force.
What is the SI of Newton?
The newton is the derived SI unit for force in the International System of Units (SI). It is defined in terms of the base SI units as kg⋅m/s² (kilogram-meter per second squared). This definition is essential for all SI units conversion involving force:
- Dyne = 10^-5 newtons
- Pound-force (lbf) ≈ 4.44822 newtons
- Kilogram-force (kgf) = 9.80665 newtons
- Kip = 1000 pound-force = 4448.22 newtons
What are Newtons Used For?
Newtons are used in a wide range of applications across physics, engineering, construction, and everyday life. As the SI unit for force measurement, newtons provide a standard for force conversion:
Physics Education
Calculating forces in mechanics problems, such as determining the weight of objects (weight = mass × gravitational acceleration). For example, a 10 kg object weighs approximately 98 newtons on Earth.
Engineering
Structural analysis, calculating loads on buildings, bridges, and machinery. For example, determining that a 500 kg load exerts a force of approximately 4903 newtons.
Manufacturing
Testing material strength, measuring forces in assembly processes, and calibrating equipment. For example, ensuring that a bolt can withstand 20000 newtons of tensile force.
Sports Science
Measuring forces exerted by athletes, such as the impact force when landing from a jump or the force generated in a punch. For example, a boxer's punch might generate 3000 newtons of force.
Etymology and History
The newton was named after Sir Isaac Newton (1643-1727), the English physicist and mathematician who formulated the laws of motion and universal gravitation. The unit was officially adopted by the General Conference on Weights and Measures (CGPM) in 1948.
Before the adoption of the newton, various units were used to measure force, including the pound-force in the imperial system and the dyne in the CGS system. The newton provided a standardized unit based on the metric system's fundamental units, making it essential for scientific and engineering work in the SI system.
Frequently Asked Questions
Why is the newton the SI unit of force?
The newton was chosen as the SI unit of force because it is directly derived from the fundamental SI units of mass (kilogram), length (meter), and time (second) through Newton's second law (F = ma). This definition provides a coherent and universally reproducible standard for force measurement in all scientific and engineering applications.
How accurate is the newton definition?
The current definition of the newton is extremely accurate, based on the precisely defined SI base units. Since 2019, the kilogram is defined by fixing the Planck constant, making the newton definition even more precise. This ensures that force measurements using newtons maintain the highest possible accuracy for scientific research and engineering applications.
What's the relationship between newtons and weight?
Weight is a force caused by gravity, and it is measured in newtons. On Earth's surface, an object's weight in newtons equals its mass in kilograms multiplied by the gravitational acceleration (approximately 9.80665 m/s²). For example, a person with a mass of 70 kg weighs about 686 newtons on Earth.
How do I convert newtons to other units?
Use our newton conversion calculators above, or multiply by the appropriate conversion factor. For example, to convert newtons to pound-force, multiply by 0.224809; to convert newtons to kilogram-force, multiply by 0.101972.

What are common uses for newton conversion?
Newton conversion is essential in physics education (calculating forces in problems), engineering (structural load analysis), manufacturing (material testing), and sports science (measuring impact forces). Whether calculating the force needed to accelerate a car or measuring the grip strength of an athlete, our newton converter tool simplifies these everyday tasks.
How does newton conversion differ from other force units?
As the SI derived unit for force, the newton is defined in terms of the fundamental SI base units (kg⋅m/s²), making it coherent with the entire metric system. Other force units like pound-force and kilogram-force are based on gravitational definitions, which makes the newton more suitable for scientific calculations and SI units conversion.
Can I convert very small or very large forces in newtons?
Yes, our newton converter handles both extremely small and large force measurements with precision. For microscopic forces, convert micronewtons to newtons (1 µN = 0.000001 N). For large forces, convert kilonewtons to newtons (1 kN = 1000 N). Our smart rounding feature ensures readable results for all scales.
Is your newton conversion tool free to use?
Yes, our newton conversion calculator is completely free with no registration required. Simply enter your value, select your target unit, and get instant, accurate results. We believe precise measurement conversion should be accessible to everyone, from students learning physics to professionals working on complex engineering projects.
