Force units: overview and conversion factors
Newton, kilopond, pound-force and dyne – physics, statics and mechanical engineering
Force is a physical quantity that accelerates, deforms, or holds a body in equilibrium. Newton's second law describes force as the product of mass and acceleration: F = m × a. The SI unit of force is the newton (N), named after Sir Isaac Newton. One newton is the force that gives a mass of 1 kilogram an acceleration of 1 m/s². The weight of a bar of chocolate (100 g) on Earth is about 0.981 N, and the weight of a litre of water (1 kg) is about 9.807 N.
In construction and structural engineering, kilonewtons (kN = 1,000 N) and meganewtons (MN = 1,000,000 N) are common. Bridges must bear loads of thousands of kilonewtons. The permitted load capacity of a 630 kg elevator corresponds to about 6.18 kN. Wind loads on buildings are given in kN/m². In mechanical engineering, bolt tightening torques and material test forces are measured in newtons or kilonewtons.
The kilopond (kp) was a force unit formerly common in German-speaking countries, replaced by the newton in 1978. 1 kp corresponds to the weight force of 1 kilogram at sea level: 1 kp = 9.80665 N. The kilopond was practical because mass and force were numerically equal – a 1 kg mass had a weight force of 1 kp. This intuitive relationship explains why kp is still used colloquially today. Technical pressures used to be given in kp/cm² (technical atmosphere, at).
In the English-speaking system, force is measured in pound-force (lbf). 1 lbf = 4.448222 N is the weight force of one pound (about 454 g). Pound-force is used in US aerospace, mechanical engineering, and for engine thrust ratings. Aircraft thrust is often measured in lbf: a typical jet engine produces 15,000–30,000 lbf of thrust (67–134 kN).
The dyne is the force unit in the outdated CGS system. 1 dyne = 10⁻⁵ N = 0.00001 N – a very small unit. In the CGS system, surface tension is given in mN/m (millinewtons per metre), which used to be expressed in dyn/cm: 1 dyn/cm = 1 mN/m. Biological and chemical applications still sometimes use dynes today, e.g. when measuring cell forces in biophysics. Our force converter covers all common units.

Frequently asked questions about the force converter
Everything about newtons, kilonewtons, kilopond, dyne and pound-force
What is a newton (N)?
One newton (N) is the force that accelerates a mass of 1 kilogram at 1 m/s² (F = m × a). The weight of a 100-gram object on Earth is about 0.981 N (0.1 kg × 9.80665 m/s²). The weight of a 1 kg mass is about 9.807 N.
What is a kilopond (kp)?
1 kilopond (kp) corresponds to the weight force of 1 kilogram on Earth: 1 kp = 9.80665 N. The kilopond is an outdated unit that used to be used in German-speaking countries for force and pressure readings. It has since been replaced by the newton, but still appears in older technical documents.
What is pound-force (lbf) and where is it used?
1 lbf (pound-force) = 4.448222 N is the weight force of one pound (454 g) on Earth. Lbf is used in English-speaking countries for force and pressure readings, e.g. in aerospace and mechanical engineering. Tire pressure in PSI (pound per square inch) is also based on lbf.
What is dyne and in which system is it used?
1 dyne = 10⁻⁵ N = 0.00001 N is the force unit in the CGS system (centimetre-gram-second). The CGS system was used before the SI system and is now outdated. 1 dyne is the force that accelerates a 1-gram mass by 1 cm/s². In physics, the dyne is still known for special applications.
How do I convert my body weight to newtons?
Your weight in newtons is calculated as mass (kg) × gravitational acceleration (9.80665 m/s²). A 75 kg person weighs 75 × 9.80665 ≈ 735.5 N ≈ 75 kp ≈ 165.3 lbf on Earth. On the Moon (gravity 1.62 m/s²), the weight would be only 75 × 1.62 ≈ 121.5 N.
