Force is a push or pull upon an object resulting from its interaction with another object. The SI unit of force is the Newton (N), defined as the force needed to accelerate 1 kilogram of mass at 1 meter per second squared. Other common units include pound-force (lbf), dyne, kilogram-force (kgf), and kip. Force is a vector quantity, meaning it has both magnitude and direction.

Understanding Force Units
Force is a fundamental physical quantity that describes the interaction between objects. It's measured in various units across different measurement systems, each with specific applications in science, engineering, and industry.
-
SI System (Newton) The Newton (N) is the SI unit of force, defined as the force needed to accelerate 1 kg at 1 m/s². Used globally in science and engineering.
-
Imperial System (Pound-Force) The pound-force (lbf) is used primarily in the United States for engineering applications. 1 lbf = 4.44822 N.
-
CGS System (Dyne) The dyne is the CGS unit of force, equal to 10⁻⁵ Newtons. Commonly used in physics and older scientific literature.
-
Gravitational (Kilogram-Force) Kilogram-force (kgf) represents the gravitational force on 1 kg of mass at Earth's surface. 1 kgf = 9.80665 N.
-
Engineering (Kip) A kip (kilopound-force) equals 1,000 lbf or 4,448.22 N. Used in structural engineering for large forces.
-
Atomic & Planck Units Atomic unit of force and Planck force are used in quantum physics and theoretical physics for extremely small or large forces.

Frequently Asked Questions
To convert Newtons to pound-force, multiply the value in Newtons by 0.224809. For example, 100 Newtons equals 22.4809 pound-force. The exact conversion factor is 1 N = 0.2248089431 lbf. Our converter does this automatically with scientific precision.
Mass is a measure of the amount of matter in an object (measured in kilograms), while force is a push or pull that causes acceleration (measured in Newtons). On Earth, 1 kg of mass experiences approximately 9.80665 Newtons of gravitational force. Mass is constant regardless of location, but weight (a force) varies with gravity.
Yes, our converter uses scientifically-verified conversion factors from NIST and ISO standards. Results are accurate to 10 significant digits, suitable for engineering calculations, scientific research, academic work, and professional applications. All conversion factors are based on the International System of Units (SI).
A dyne is the CGS (centimeter-gram-second) unit of force. One dyne equals 10⁻⁵ Newtons, or 0.00001 N. It's commonly used in physics and older scientific literature. To convert dynes to Newtons, divide by 100,000. For example, 1,000,000 dynes = 10 Newtons.
A kip (kilopound-force) equals 1,000 pound-force or approximately 4,448.22 Newtons. It's primarily used in structural engineering in the United States for measuring large forces like building loads, bridge stresses, and foundation pressures. The term "kip" comes from "kilo-pound."
To convert kilogram-force (kgf) to Newtons, multiply by 9.80665. This is the standard acceleration due to gravity on Earth. For example, 10 kgf = 98.0665 N. Note that kilogram-force is a gravitational unit, while Newton is an absolute unit of force.
The atomic unit of force is approximately 8.2387 × 10⁻⁸ Newtons. It's derived from fundamental constants and used in quantum mechanics and atomic physics. It represents the force between an electron and proton in a hydrogen atom at the Bohr radius.
Planck force is approximately 1.2103 × 10⁴⁴ Newtons. It's derived from Planck units and represents an extremely large force used in theoretical physics, particularly in quantum gravity and cosmology. It's the force that would accelerate 1 Planck mass at 1 Planck acceleration.

A sthene (also spelled sthène) is a metric unit of force equal to 1 kilonewton (1,000 N). It was proposed in the early 20th century as part of the meter-tonne-second system but never gained widespread adoption. It's occasionally seen in older European engineering literature.
