Millinewton to Kip Converter

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 × 10⁶ dynes

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.
