What is a Metric Ton-force and a Kilonewton?

Metric ton-force (tf) is the force exerted by one metric ton (tonne = 1,000 kg) under standard gravity (9.80665 m/sĀ²).

Formula: 1 tf = 1,000 kg Ɨ 9.80665 m/sĀ²

Conversions:

  • 1 tf = 9,806.65 N (newtons)
  • 1 tf = 9.80665 kN (kilonewtons)
  • 1 tf = 2,204.62 lbf (pounds-force)
  • 1 tf = 1,000 kgf (kilogram-force)
  • 1 tf = 0.00980665 MN (meganewtons)
  • 1 tf = 2.20462 kip

The kilonewton (kN) is equal to 1,000 newtons. It measures force in the SI system at a practical scale for engineering.

Formula: 1 kN = 1,000 N = 1,000 kgā‹…m/sĀ²

Conversions:

  • 1 kN = 1,000 N (newtons)
  • 1 kN = 0.001 MN (meganewtons)
  • 1 kN = 224.809 lbf (pounds-force)
  • 1 kN = 101.97 kgf (kilogram-force)
  • 1 kN = 0.2248 kip (1000 lbf)
  • 1 kN = 1,000,000 mN (millinewtons)

Note: The Metric Ton-force is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Kilonewton belongs to the imperial/US customary system.

History of the Metric Ton-force and Kilonewton

Metric ton-force emerged from the meter-kilogram-second gravitational system as a practical unit for measuring large forces in metric countries. The metric ton (tonne) equals 1,000 kilograms, making ton-force a natural extension of kilogram-force for heavy loads. Widely used in European, Asian, and Latin American engineering throughout the 20th century for crane ratings, structural loads, and industrial equipment specifications. While SI standardization favors kilonewtons, metric ton-force remains common in practical engineering contexts where the intuitive relationship to mass (1 tonne = 1 tf on Earth) provides convenience.

The kilonewton emerged when the newton was adopted as the SI unit of force in 1948 at the 9th General Conference on Weights and Measures. As the SI system gained international acceptance in the 1960s through 1980s, the kilonewton became the standard unit for structural engineering calculations, replacing various regional units like the ton-force and kip. Today, kN is universally used in building codes, structural design software, equipment specifications, and engineering documentation worldwide. The unit provides a convenient scale where typical structural loads fall in the range of 1-1000 kN.
