How to convert newtons to kilograms-force
Kilogram-force and pound-force use standard gravity 9.80665 m/s². A kilogram or pound of mass is a different quantity; local weight depends on local gravity.
Use x for the value in N, b for the intermediate value in N, and y for the result in kgf.
kgf = N ÷ 9.80665
Worked examples
10 N ≈ 1.01971621298 kgf
Step 1: (10 × 1) ≈ 10 N.
Step 2: 10 ÷ 9.80665 ≈ 1.01971621298 kgf.20 N ≈ 2.03943242596 kgf
Step 1: (20 × 1) ≈ 20 N.
Step 2: 20 ÷ 9.80665 ≈ 2.03943242596 kgf.
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Newtons
Newtons (N) measures force under the conventions above. The base value in N is (x × 1), where x is the numerical value in N. Factors shown here are rounded for display; calculations use the stored factor.
About Kilograms-force
Kilograms-force (kgf) measures force under the conventions above. The base value in N is (x × 9.80665), where x is the numerical value in kgf. Factors shown here are rounded for display; calculations use the stored factor.
