What is a Metric Ton-force and a Gram-force?

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

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)

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 Gram-force belongs to the metric (SI) system.

History of the Metric Ton-force and Gram-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.

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.
