What is a Metric Ton-force?

Metric ton-force (tf) is the force exerted by one metric ton (1,000 kg) of mass under standard Earth gravity. Equal to 9,806.65 newtons or 9.80665 kilonewtons, it is used in heavy engineering, construction, and industrial applications.

History of the Metric Ton-force

Emerged from the metric gravitational system as a practical unit for large forces. Also called tonne-force. Common in European and Asian engineering before widespread SI adoption. Still used alongside kilonewtons in many engineering contexts.

Quick Answer

What is Metric Ton-force? A metric ton-force (tf) is the force exerted by a one-metric-ton (1,000 kg) mass in Earth's standard gravity. 1 tf = 9,806.65 newtons = 9.80665 kilonewtons = 2,204.6 pounds-force. Used in heavy engineering for crane capacities, structural loads, industrial equipment ratings, and construction specifications. Common in metric countries for large force measurements.

Definition

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 × 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

History

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
