What is a Kilogram-force and a Pound-force?

Kilogram-force (kgf) is the force exerted by one kilogram of mass under standard gravity (9.80665 m/s²).

Formula: 1 kgf = 1 kg × 9.80665 m/s²

Conversions:

  • 1 kgf = 9.80665 N (newtons)
  • 1 kgf = 0.00980665 kN (kilonewtons)
  • 1 kgf = 2.204623 lbf (pounds-force)
  • 1 kgf = 1,000 gf (gram-force)
  • 1 kgf = 980,665 dynes
  • 1 kgf = 35.274 ozf (ounce-force)

Pound-force (lbf) is the force exerted by one pound of mass under standard gravity (32.174 ft/s² or 9.80665 m/s²).

Conversions:

  • 1 lbf = 4.448222 N
  • 1 lbf = 0.453592 kgf
  • 1000 lbf = 1 kip
  • 1 lbf = 4.448 × 10⁵ dynes

Note: The Kilogram-force is part of the metric (SI) system, primarily used globally in science and trade. The Pound-force belongs to the imperial/US customary system.

History of the Kilogram-force and Pound-force

Kilogram-force emerged from the meter-kilogram-second gravitational system (MKS), which was used extensively in engineering before the adoption of SI units in the 1960s. In German-speaking countries and parts of Europe, it was called "kilopond" (kp), from the Latin word for weight. Despite the official adoption of the newton as the SI unit of force in 1960, kilogram-force remains prevalent in many engineering disciplines, particularly in automotive torque specifications, hydraulic systems, material testing, and construction equipment. Many Asian and European countries continue to use kgf in technical documentation and consumer products.

Common Uses and Applications: kilograms-force vs pounds-force

Explore the typical applications for both Kilogram-force (metric) and Pound-force (imperial/US) to understand their common contexts.

Common Uses for kilograms-force

Automotive Engineering: Torque specifications (kgf·m), suspension loads, brake force.

Hydraulic Systems: Pressure ratings (kgf/cm² = 1 technical atmosphere).

Material Testing: Tensile strength, compression testing, hardness measurements.

Construction: Structural loads, lifting equipment capacity, crane ratings.

Consumer Products: Weight capacity labels, exercise equipment resistance.

When to Use pounds-force

Automotive: Weight specifications, brake force, suspension loads, torque specs. Aerospace: Thrust ratings (jet engines rated in lbf), structural loads. Structural Engineering: Building loads, beam capacity (often in kips = 1000 lbf), foundation design. Mechanical: Bolt torque specs, spring rates, tool forces, clamp pressure. Hydraulics: Actuator force ratings, pump specifications.
