What is a Ounce-force and a Kip?

Ounce-force (ozf) is the force exerted by one avoirdupois ounce of mass under standard gravity (32.174 ft/s²).

Formula: 1 ozf = 1 oz Ɨ 32.174 ft/s²

Conversions:

  • 1 ozf = 0.278014 N (newtons)
  • 1 ozf = 0.0625 lbf (1/16 pound-force)
  • 1 ozf = 28.35 gf (gram-force)
  • 1 ozf = 0.02835 kgf (kilogram-force)
  • 1 ozf = 278,014 dynes
  • 16 ozf = 1 lbf

A kip equals 1,000 pounds-force. It is a standard unit in US structural engineering.

Formula: 1 kip = 1,000 lbf

Conversions:

  • 1 kip = 1,000 lbf (pounds-force)
  • 1 kip = 4,448.222 N (newtons)
  • 1 kip = 4.448222 kN (kilonewtons)
  • 1 kip = 453.592 kgf (kilogram-force)
  • 1 kip = 0.5 ton-force (US short ton)
  • 1 kip = 4.448 Ɨ 10⁶ dynes

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

History of the Ounce-force and Kip

Ounce-force derives from the avoirdupois ounce, part of the imperial system developed in medieval England for commerce. The ounce (1/16 of a pound) was standardized for general goods, distinguishing it from the troy ounce used for precious metals. As a force unit, ounce-force became common in applications requiring finer precision than pounds, such as pharmacy scales, postal scales, and small mechanical springs. While metric units have largely replaced ozf in scientific and international contexts, it persists in US consumer products, food packaging, fishing equipment, and some mechanical specifications.

The kip was introduced in American structural engineering during the early 20th century as building sizes increased and forces became too large for convenient expression in pounds. The term combines "kilo-" (meaning thousand) with "pound" to create "kip." It became standardized in US building codes, structural steel design manuals, and engineering textbooks. Organizations like the American Institute of Steel Construction (AISC) and American Concrete Institute (ACI) use kips as the primary force unit in their design specifications. While the rest of the world uses kilonewtons, American engineers continue to work primarily in kips for structural calculations.

Additional Unit Information

About Ounce-force (ozf)

How do I convert ounce-force to newtons?

Formula: N = ozf Ɨ 0.278014

Examples:

  • 1 ozf = 0.278 N
  • 4 ozf = 1.11 N
  • 16 ozf = 4.45 N
  • 32 ozf = 8.90 N

Quick approximation: Multiply by 0.28 for rough conversion.

How many ounce-force equal one pound-force?

1 pound-force = 16 ounce-force

Quick conversions:

  • 0.25 lbf = 4 ozf
  • 0.5 lbf = 8 ozf
  • 1 lbf = 16 ozf
  • 2 lbf = 32 ozf

Reverse: 1 ozf = 0.0625 lbf (1/16 of a pound-force)

What is the difference between ounce and ounce-force?

Ounce (oz): Unit of MASS - measures amount of matter.

Ounce-force (ozf): Unit of FORCE - measures weight or push/pull.

Relationship: On Earth at standard gravity, 1 ounce of mass exerts 1 ounce-force.

Important distinction: In space (zero gravity), a 1-ounce mass still has 1 ounce of mass but exerts 0 ounce-force. On the Moon, it would exert ~0.17 ozf due to lower gravity.

Note: In everyday US usage, "ounce" typically refers to weight (force), but in physics and engineering, the distinction matters.

What is a troy ounce-force?

Troy ounce-force is based on the troy ounce (31.1 grams), used for precious metals:

  • 1 troy ozf = 0.305 N
  • 1 troy ozf = 1.097 avoirdupois ozf
  • 1 troy ozf = 31.1 gf

Avoirdupois ounce-force (standard ozf) is based on the avoirdupois ounce (28.35 grams), used for general goods.

Most force applications use avoirdupois ounce-force unless specifically dealing with precious metals or pharmacy.

About Kip (kip)

How do I convert kips to pounds-force?

Formula: lbf = kip Ɨ 1,000

Examples:

  • 0.5 kip = 500 lbf
  • 1 kip = 1,000 lbf
  • 5 kip = 5,000 lbf
  • 10 kip = 10,000 lbf

Simple rule: Multiply by 1,000 or add three zeros.

Kips to Pounds-force converter →

How many kips equal one kilonewton?

1 kilonewton = 0.2248 kips (approximately 0.225 kips)

Quick conversions:

  • 1 kN = 0.225 kip
  • 10 kN = 2.25 kip
  • 100 kN = 22.5 kip
  • 1,000 kN = 225 kip

Reverse: 1 kip = 4.448 kN

Kilonewtons to Kips converter →

Why do American engineers use kips instead of kilonewtons?

Historical practice: Kips have been standard in US engineering since the early 1900s.

Building codes: US codes (IBC, ASCE 7) specify loads in pounds and kips.

Engineering education: American universities teach structural design in kips.

Industry standards: AISC Steel Manual, ACI Concrete Code use kips.

Existing infrastructure: Decades of drawings, specifications, and software use kips.

Convenience: For US engineers working in imperial units, kips integrate naturally with feet, inches, and pounds per square foot.

While metric units (kN) are standard internationally, the kip remains deeply embedded in American structural engineering practice.

What is a kip per square inch (ksi)?

ksi = kips per square inch - a unit of stress or pressure.

Common use: Material strength specifications

  • Structural steel: 36-100 ksi yield strength
  • Concrete: 3-10 ksi compressive strength
  • Aluminum: 30-70 ksi tensile strength

Conversion: 1 ksi = 6.895 MPa (megapascals)

Note: ksi is to stress what kip is to force - a convenient large unit avoiding excessive digits.
