Kilonewtons to Kilograms-force Converter

To convert a measurement in kilonewtons to kilograms-force, multiply the value by 101.971621. The conversion factor comes from the relationship between both units and the newton.

For example, to convert 5 kN to kilograms-force: 5 × 101.971621 = 509.858106 kgf.

A kilonewton is a metric unit of force equal to 1,000 newtons. One kilonewton is roughly the weight of a 102 kg mass under standard gravity. The kilonewton became the practical working unit in civil and structural engineering because typical loads on beams, foundations, and cables are far larger than a single newton.

Common uses of kilonewtons include: Structural engineering loads and reactions; Crane and hoist capacity ratings; Climbing and rigging equipment strength ratings; Vehicle and aircraft thrust specifications.

A kilogram-force is the force exerted by gravity on a mass of one kilogram under standard gravity, equal to exactly 9.80665 newtons. The kilogram-force (also called the kilopond) was common in older metric engineering before the SI newton became standard. It is still encountered in tire pressure, thrust, and legacy technical documents.

Common uses of kilograms-force include: Legacy metric engineering documentation; Thrust ratings expressed in kgf (aviation); Spring and load-cell calibration; Everyday 'weight as force' descriptions.

Here are some common values converted:

1 kN = 101.971621 kgf 5 kN = 509.858106 kgf 10 kN = 1,019.7162 kgf 50 kN = 5,098.5811 kgf 100 kN = 10,197.1621 kgf
