kgf to Newtons – Fast Conversion Guide

Convert kilogram-force (kgf) to Newtons (N) by multiplying by 9.80665 (standard gravity). Reverse: kgf = N ÷ 9.80665.

Formulas

N = kgf × 9.80665
kgf = N ÷ 9.80665
(1 kgf = weight of 1 kg at standard gravity)

Quick Values

1 kgf = 9.80665 N · 5 kgf = 49.033 N · 10 kgf = 98.0665 N · 50 kgf = 490.33 N · 100 kgf = 980.665 N.

Example (12 kgf)

Apply: 12 × 9.80665 = 117.6798 N
Rounded (2 dp): 117.68 N
Reverse check: 117.6798 ÷ 9.80665 ≈ 12.000 kgf
Answer: 12 kgf ≈ 117.68 N

Uses

Legacy specifications expressed in kgf
Mechanical test stands (spring / press ratings)
Ergonomics & lifting equipment documentation
Translating lab data to SI force units

Accuracy & Tips

Use 9.80665 (standard gravity); avoid 9.81 for precision specs
kgf is not SI—prefer Newtons in formal reports
Round to match original kgf significant figures
Local gravity variation changes true weight slightly

FAQ

kg vs kgf? kg = mass, kgf = force due to gravity on that mass.
Why 9.80665? Defined standard gravity for consistency.
Quick mental? N ≈ kgf × 10 (slightly high) then subtract ~2%.
Use in specs? Convert to N unless legacy format required.
