Convert Torque Units Without Guesswork

Torque values are often listed in pound-inch (lb-in), especially in tools and mechanical manuals from the US. However, many regions and industries prefer kilogram-force (kgf) based units. A reliable Inch to Kg Calculator removes the need for manual conversions and avoids costly mistakes in mechanical assembly.

This calculator handles all common torque units and provides accurate conversions for both imperial and metric systems.

Conversion Formula

The conversion follows a two-step process:

Step 1: lb-in to Newton-meters
1 lb-in = 0.113 Nm
Step 2: Nm to kgf-m
1 Nm = 0.10197 kgf-m

Combined into a single formula:

kgf-m = lb-in × 0.01152
Direct conversion formula

For reverse conversion:

lb-in = kgf-m ÷ 0.01152
Reverse conversion formula
