How to Convert Pound-force to Kip
- 1 lbf = 0.001 kip
- 1 kip = 1000 lbf
- Example: convert 15 lbf to kip: 15 lbf = 15 × 0.001 kip = 0.015 kip
Formula
kip = lbf ÷ 1000
Derivation from SI units:
- 1 lbf = 0.45359237 kg × 9.80665 m/s² = 4.4482216152605 N
- 1 kip = 1000 lbf = 4448.2216152605 N
- 1 lbf = 4.448221615261 N ÷ 4448.221615261 N per kip = 0.001 kip
Both units are defined exactly, so the factor is exact. Pound-force definition: pound-force; Kip definition: kip.
Worked examples
- A reading of 25 lbf converts to 0.025 kip.
25 lbf × 0.001 = 0.025 kip - A value of 500 lbf is 0.5 kip.
500 lbf × 0.001 = 0.5 kip

Frequently asked questions
How many kips are in 1 pound-force?
1 lbf = 0.001 kip.
How do I convert pounds-force to kips?
Multiply the value in lbf by 0.001, or divide it by 1000. For example, 15 lbf × 0.001 = 0.015 kip.
Is the lbf to kip conversion exact?
Yes. Both units are defined exactly, and 1 lbf is exactly 0.001 kip.
