What is a Pound-force and a Metric Ton-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 Ɨ 10⁵ dynes

Metric ton-force (tf) is the force exerted by one metric ton (tonne = 1,000 kg) under standard gravity (9.80665 m/s²).

Formula: 1 tf = 1,000 kg Ɨ 9.80665 m/s²

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

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

History of the Pound-force and Metric Ton-force

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.

Common Uses and Applications: pounds-force vs metric tons-force

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

Common Uses for pounds-force

Automotive: Weight specifications, brake force, suspension loads, torque specs. Aerospace: Thrust ratings (jet engines rated in lbf), structural loads.
