Understanding Torque Conversion: Nm to in-lbs
What is Torque?
Torque is a rotational force that causes objects to turn around an axis. It's the twisting force applied to fasteners, bolts, and rotating components. Proper torque application is crucial for safety and performance in mechanical assemblies.
Why Convert Nm to in-lbs?
- •Different regions use different torque units
- •Tool specifications may differ from manual specs
- •International collaboration requires unit conversion
- •Quality control and documentation standards
