The Force Converter (General) is a comprehensive tool for converting between all major units of force used in science, engineering, and everyday applications. Whether you need to convert newtons to pounds-force, kilograms-force to dynes, or any other combination, this converter delivers instant, precise results.
Force is a fundamental quantity in physics, defined by Newton's second law as mass times acceleration (F = ma). The International System of Units (SI) defines the newton as the base unit of force: the force required to accelerate one kilogram of mass at one meter per second squared. However, many other force units remain in widespread use across different fields and regions.
The pound-force (lbf) is standard in American engineering and construction. The kilogram-force (kgf), also called kilopond, is commonly used in European mechanical engineering and in specifications for fastener torque, spring rates, and material testing. The dyne, the CGS unit of force, appears in older scientific literature and some specialized fields like surface tension measurement. The poundal, a rarely used absolute unit in the foot-pound-second system, eliminates the need for gravitational conversion factors. The kip (kilopound-force, 1000 lbf) is standard in structural engineering for beam loads and column capacities. The sthene, the MTS (metre-tonne-second) unit of force, equals 1000 newtons and is occasionally encountered in European engineering contexts.
Our converter supports 7 force units and uses a two-step conversion process through newtons (the SI standard) to ensure accuracy across all 42 possible unit combinations. Every conversion factor is traceable to international metrology standards, guaranteeing reliable results for professional engineering calculations, academic work, and practical applications alike.
The converter works by first converting the input value to newtons (the SI unit of force), then converting from newtons to the desired target unit. This two-step hub-and-spoke approach ensures maximum accuracy across all unit pairs.
Key conversion factors to newtons: 1 lbf = 4.44822 N, 1 kgf = 9.80665 N (exact, based on standard gravity), 1 dyn = 10-5 N (exact), 1 pdl = 0.138255 N, 1 kip = 4448.22 N, 1 sn = 1000 N (exact).
Force values vary enormously across applications. A human finger press is about 1 N, your body weight might be 700 N (≈ 157 lbf), a car engine produces around 2000-4000 N of thrust, and structural beams in buildings support loads measured in kips (thousands of pounds-force). Always verify units when working with engineering specifications, as confusing force units has caused notable engineering failures.

A newton is roughly the force of gravity on a small apple (about 100 grams). It takes about 1 N of force to accelerate 1 kg at 1 m/s². A person weighing 70 kg exerts about 686 N of gravitational force.
A kilogram-force (kgf) is the force exerted by 1 kg under standard gravity (9.80665 m/s²). So 1 kgf = 9.80665 N exactly. The kgf is gravitationally defined, while the newton is a fundamental SI unit independent of gravity.
A kip equals 1000 pounds-force. Structural engineers use kips to avoid writing large numbers when specifying beam loads, column capacities, and foundation reactions that commonly reach thousands or millions of pounds.
The dyne (1 dyn = 10⁻⁵ N) is the CGS unit of force. It appears in surface tension measurements (dynes/cm), older physics literature, and some specialized scientific fields. Most modern work uses newtons.
The poundal is the force required to accelerate 1 pound of mass at 1 foot per second squared. It equals approximately 0.138255 N. It is rarely used today but appears in some historical engineering texts.
Weight is a force: W = mg. Multiply mass (kg) by gravitational acceleration (9.80665 m/s²) to get force in newtons. For pounds, mass in slugs × 32.174 ft/s² = force in pounds-force.
The sthene (sn) is the force unit in the metre-tonne-second (MTS) system. 1 sn = 1000 N = 1 kN. It was historically used in some European engineering contexts but is rarely encountered today.
No. Pound-force (lbf) is a unit of force equal to the gravitational force on one pound-mass at standard gravity. At Earth's surface, 1 lbm weighs approximately 1 lbf, but they measure different physical quantities.
All conversions use internationally standardized factors. The kgf conversion is exact (based on g = 9.80665 m/s²). Other factors are precise to at least 6 significant figures, matching or exceeding typical engineering requirements.
No, force and torque are different quantities. Torque = force × distance, measured in newton-meters or foot-pounds. Use our dedicated Torque Converter for torque unit conversions.
