About Converting Kips to Attonewtons
Kip and Attonewton both measure force, and the conversion matters whenever an SI-trained engineer needs to compare notes with a US-trained one, or vice versa. Specifically: A kip is 1,000 pound-force, and attonewton is 1e-18 newton units.
Formula
attonewtons = kips × 4.448222e+21
This factor comes from each unit's defined relationship to the category's base unit: 1 kip equals 4448.22161526 base units, and 1 attonewton equals 1e-18 base units, so dividing one by the other gives the direct kip-to-attonewton factor of 4.448222e+21.
Simple example
1 kip × 4.448222e+21 = 4.448222e+21 aN
1 kip = 4.448222e+21 attonewtons.
Real-world example
10 kip × 4.448222e+21 = 4.448222e+22 aN
10 kips = 4.448222e+22 attonewtons.
