Torque Converter

Convert torque between n·m, ft·lb, in·lb and kgf·m.

How the Math Works

The Torque Converter uses a base-unit conversion formula where the result equals the input value multiplied by the from-unit's base conversion factor, then divided by the to-unit's base conversion factor. This works because all torque units (N·m, ft·lb, in·lb, kgf·m) can be expressed as multiples of a standard reference unit. By converting both the source and target units to their respective base values, the calculator creates a proportional relationship that accurately scales the torque measurement across different systems.

Practical Applications

To use this converter practically, first determine which torque unit your specific application requires. For automotive work, you might convert between ft·lb and N·m when using different torque wrenches or checking manufacturer specifications. In engineering projects, you may need to switch between metric (N·m) and imperial (in·lb) units when collaborating with international teams or ordering components with different specification standards. Simply enter your known torque value and select the target unit to get the precise conversion.

Day-to-Day Use

Torque conversions become essential in everyday mechanical tasks like automotive maintenance, furniture assembly, or DIY projects. When you're tightening a bolt to the manufacturer's recommended specification but your torque wrench reads in different units, this converter bridges the gap between your tools and the required force. It's particularly valuable when shopping for hardware online—where products might list torque ratings in N·m while your garage tools use ft·lb—ensuring you apply the correct tightening force to prevent damage or failure.
