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)
Pound-force (lbf) is the force exerted by one pound of mass under standard gravity (32.174 ft/sĀ² or 9.80665 m/sĀ²).
Conversions:
- 1 lbf = 4.448222 N
- 1 lbf = 0.453592 kgf
- 1000 lbf = 1 kip
- 1 lbf = 4.448 Ć 10āµ 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 Pound-force belongs to the imperial/US customary system.
History of the US Ton-force and Pound-force
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.
Common Uses and Applications: US tons-force vs pounds-force
Explore the typical applications for both US Ton-force (imperial/US) and Pound-force (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 pounds-force
Automotive: Weight specifications, brake force, suspension loads, torque specs. Aerospace: Thrust ratings (jet engines rated in lbf), structural loads. Structural Engineering: Building loads, beam capacity (often in kips = 1000 lbf), foundation design. Mechanical: Bolt torque specs, spring rates, tool forces, clamp pressure. Hydraulics: Actuator force ratings, pump specifications.
