What is a Millinewton and a Kilogram-force?

The millinewton (mN) equals 0.001 newtons. It measures small forces in SI units.

Formula: 1 mN = 0.001 N = 10⁻³ kg⋅m/s²

Conversions:

  • 1 mN = 0.001 N (newtons)
  • 1 mN = 1,000 μN (micronewtons)
  • 1 mN = 0.000224809 lbf (pounds-force)
  • 1 mN = 0.10197 gf (gram-force)
  • 1 mN = 100 dynes
  • 1,000 mN = 1 N

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 Millinewton is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Kilogram-force belongs to the metric (SI) system.

History of the Millinewton and Kilogram-force

The millinewton emerged as precision measurement technology advanced in the 20th century. As instruments capable of measuring small forces were developed for materials science, electronics testing, and biological research, a convenient SI unit was needed. The millinewton provides an appropriate scale for forces that are too small to express conveniently in newtons but don't require the microscale precision of micronewtons. It gradually replaced the CGS unit dyne in modern scientific literature while maintaining SI unit consistency. Today, mN is standard in surface tension measurements, precision force gauges, and microelectronics testing.

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.
