My car manual shows 20 kgf·m torque. What's that in lbf·ft for my American tools?

20 kgf·m × 2.2046 = 44.1 lbf·ft. Always verify units when using international vehicle specs; mixing units causes mechanical failures.

What's the difference between kgf and lbf?

1 kgf = force of 1 kg under gravity ≈ 9.81 N. 1 lbf = force of 1 lb under gravity ≈ 4.45 N. 1 kgf ≈ 2.2 lbf. kgf is metric/industrial; lbf is American/mechanical.

A hydraulic system rated 500 kgf—is that force or pressure?

That's force (or a load rating). 500 kgf ≈ 1,102 lbf. Pressure would be kgf/cm² (or lbf/in²/psi). Different units for different things; always check context.

Why do European cars use kgf·m for torque instead of lbf·ft?

Europe uses SI/metric units. 1 kgf·m is practical for engines (often 15–30 range). lbf·ft is US standard. 1 kgf·m = 7.233 lbf·ft. Both express rotational force the same way. See [pound-force to kilogram-force]({/force/lbf-to-kgf/}) for direct force comparisons.

Key Formulas

Newton → Pound-Force

lbf = N × 0.224809

Pound-Force → Newton

N = lbf × 4.44822

Kilogram-Force → Newton

N = kgf × 9.80665

Newton → Kilogram-Force

kgf = N × 0.101972

Formula

lbf = kgf × 2.204623

Kilogram-force is used in automotive and industrial specs (engine torque, hydraulic pressure); pounds-force is the American engineering standard. Converting between them is essential when working with international equipment manuals or comparing specifications across metric and imperial systems.
