US ton-force (short ton-force) is the force exerted by one short ton (2,000 pounds) under standard gravity.
Formula: 1 tonf = 2,000 lbf = 2 kip
Conversions:
- 1 tonf = 8,896.44 N (newtons)
- 1 tonf = 8.89644 kN (kilonewtons)
- 1 tonf = 2,000 lbf (pounds-force)
- 1 tonf = 2 kip (kilopounds)
- 1 tonf = 907.185 kgf (kilogram-force)
- 1 tonf = 0.907185 metric ton-force
- 1 tonf = 0.892857 UK ton-force (long ton-force)
The dyne (dyn) is the CGS unit of force. 1 dyne = force to accelerate 1 gram mass at 1 cm/s².
Formula: F = ma (Force = mass × acceleration in CGS units)
Conversions:
- 1 dyne = 0.00001 N (10⁻⁵ newtons)
- 1 dyne = 0.00000224809 lbf (pounds-force)
- 1 dyne = 0.00000102 kgf (kilogram-force)
- 100,000 dynes = 1 N
- 1 N = 10⁵ dynes
Note: The US Ton-force is part of the imperial/US customary system, primarily used in the US, UK, and Canada for everyday measurements. The Dyne belongs to the imperial/US customary system.
History of the US Ton-force and Dyne
The US ton-force is based on the short ton of 2,000 pounds, the standard ton in the United States. The short ton (as opposed to the UK's long ton of 2,240 pounds) became standardized in American commerce and industry in the 19th century. As a force unit, ton-force provides a convenient scale for heavy loads in US engineering, particularly in construction equipment, crane capacities, and structural design. It is closely related to the kip (1,000 lbf), with 1 ton-force = 2 kips. While international engineering uses kilonewtons, US ton-force remains common in American construction, heavy industry, and equipment specifications.
The dyne was introduced in the 1870s as part of the CGS (centimeter-gram-second) system developed by the British Association for the Advancement of Science. The name derives from the Greek word "dynamis" meaning power or force. While the CGS system was widely used in physics throughout the 19th and early 20th centuries, it has been largely superseded by the SI system and the newton. However, dynes still appear in surface tension measurements, older scientific literature, and certain physics contexts where CGS units remain conventional.
Common Uses and Applications: US tons-force vs dynes
Explore the typical applications for both US Ton-force (imperial/US) and Dyne (imperial/US) to understand their common contexts.
Common Uses for US tons-force
Construction Equipment: Crane capacity, lifting equipment, heavy machinery ratings.
Structural Engineering: Large building loads, bridge components, foundation design.
Industrial Equipment: Press capacity, forging equipment, material handling.
Marine Engineering: Ship displacement, anchor forces, dock equipment.
Automotive: Heavy vehicle specifications, towing capacity, load ratings.
When to Use dynes
Physics Education: Teaching fundamental force concepts and unit systems - how different systems work. Surface Tension: Measured in dynes/cm (equivalent to mN/m in SI) - standard in fluid mechanics. Historical Scientific Papers: Many pre-1960s physics papers use CGS units - understanding legacy research. Microscopic Forces: Useful scale for cellular mechanics and microfluidics - avoids decimal notation. Biophysics: Cell mechanics, protein interactions, biomolecule forces.
Additional Unit Information
About Dyne (dyn)
How do I convert dynes to newtons?
Formula: N = dynes × 0.00001 (or dynes ÷ 100,000)
Examples:
- 1,000 dynes = 0.01 N
- 10,000 dynes = 0.1 N
- 100,000 dynes = 1 N
- 1,000,000 dynes = 10 N
How many dynes equal one newton?
1 newton = 100,000 dynes (10⁵ dynes)
Quick conversions:
- 0.01 N = 1,000 dynes
- 0.1 N = 10,000 dynes
- 1 N = 100,000 dynes
- 10 N = 1,000,000 dynes
The large conversion factor reflects the difference between CGS (gram, centimeter) and SI (kilogram, meter) base units.
Why is the dyne still used?
Historical reasons: Older scientific literature and textbooks use CGS units.
Surface tension: Dynes/cm is equivalent to mN/m but remains common terminology.
Convenience: For microscopic forces, dynes avoid very small decimal values.
Education: Helps students understand different unit systems and conversions.
Most modern applications have transitioned to SI units (newtons), but dynes persist in specialized contexts and legacy measurements.
What is a dyne in everyday terms?
1 dyne is:
- Force to accelerate 1 gram at 1 cm/s²
- Weight of about 1 milligram under Earth gravity
- About 1/100,000 of a newton
- Roughly the force of a small breeze on your fingertip
Perspective:
- Too small to feel directly
- Relevant for microscopic and cellular forces
- Useful in physics calculations with CGS units
- Common in surface chemistry and biophysics
