About
Kilogram-force (kgf), also known as the kilopond (kp), is a gravitational metric unit of force. While standard Newtons are preferred in modern physics, kgf remains deeply embedded in legacy civil engineering diagrams, older machinery specifications, and aerospace thrust data. It represents the force exerted by one kilogram of mass in standard earth gravity.
This tool is tailored for engineers reviewing older structural plans or converting component specs. It includes a "Safety Factor" feature, allowing you to instantly project the design load required based on a raw converted value. This eliminates the secondary calculation step often performed manually, reducing the risk of arithmetic error in critical load-bearing assessments.
Formulas
The conversion assumes standard gravity g ≈ 9.80665 m/sยฒ. The formula relates force F in Newtons to Kilogram-force:
When applying a Safety Factor (SF), the Design Load is calculated as:
