Newtons to Kilogram-force (kgf) – Quick Guide

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

Formulas

kgf = N ÷ 9.80665
N = kgf × 9.80665
Quick mental: kgf ≈ N ÷ 10 (slightly low) adjust +2%

Quick Values

9.80665 N = 1 kgf · 49.033 N ≈ 5 kgf · 98.0665 N ≈ 10 kgf · 490.333 N ≈ 50 kgf · 980.665 N ≈ 100 kgf.

Example (245.166 N)

kgf = 245.166 ÷ 9.80665 = 25.0000…
Rounded (2 dp): 25.00 kgf
Reverse check: 25 × 9.80665 = 245.166 N
Result: 245.166 N = 25 kgf

Uses

Legacy equipment specs in kgf
Load cell & spring scale readings
Ergonomic / lifting force comparisons
Converting lab force to weight equivalent

Accuracy & Tips

Use full 9.80665 for precision; 9.81 acceptable for rough work
kgf is not SI—prefer Newtons in formal documents
Keep significant figures consistent with input force
Local gravity variation changes true weight slightly

FAQ

kgf vs kg? kg = mass; kgf = force (weight) of that mass at standard gravity.
Why 9.80665? Defined standard gravity; ensures consistent calculations.
Quick mental? Divide by ~10 then add ~2%.
Is kgf obsolete? Mostly legacy—retain when matching older specs.
