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

Gram-force (gf) is the force exerted by one gram of mass under standard gravity (9.80665 m/s²).

Formula: 1 gf = 1 gram × 9.80665 m/s²

Conversions:

1 gf = 0.00980665 N (newtons)
1 gf = 9.80665 mN (millinewtons)
1 gf = 980.665 dynes
1 gf = 0.001 kgf (kilogram-force)
1 gf = 0.00220462 lbf (pounds-force)
1 gf = 0.035274 ozf (ounce-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)

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

History of the Gram-force and Kilogram-force

Gram-force emerged from the metric gravitational system of units, which was widely used in continental Europe before the adoption of SI units. The unit is also known as "gram-weight" or "pond" (from the Latin word for weight). While it remains in common use for consumer scales, spring specifications, and small mechanical devices, scientific and engineering applications increasingly prefer SI units like millinewtons. The gram-force is particularly persistent in industries like watchmaking, jewelry, and precision instruments where tradition and existing equipment favor its continued use.

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.
