About Torque Converter
Our Torque Converter is a comprehensive tool designed to convert torque measurements between various units used in engineering, automotive, and industrial applications. Torque is a measure of rotational force that causes an object to rotate about an axis or pivot point.
The tool supports conversions between Newton-meters (N·m), Pound-feet (lbf·ft), Pound-inches (lbf·in), Kilogram-force meters (kgf·m), Kilogram-force centimeters (kgf·cm), Dyne centimeters (dyn·cm), Ounce-force inches (ozf·in), and Ounce-force feet (ozf·ft). Whether you're working on automotive specifications, mechanical engineering designs, or physics calculations, this tool provides accurate conversions across all commonly used torque units.
Torque is fundamental in many fields including automotive engineering (engine torque specifications), mechanical design (bolt tightening torques), robotics (motor torque calculations), and manufacturing (fastener torque requirements). Understanding and converting between different torque units is essential for engineers, mechanics, and technicians worldwide.

Frequently Asked Questions
What is torque?
Torque is a measure of the rotational force applied to an object. It is the product of force and the perpendicular distance from the axis of rotation to the line of action of the force. In simple terms, torque describes how much "twisting force" is being applied to rotate something around an axis.
What are the different torque units?
Newton-meter (N·m): The SI unit of torque, commonly used in scientific and engineering contexts worldwide. Pound-foot (lbf·ft): Used primarily in the US and UK, especially in automotive applications. Pound-inch (lbf·in): Used for smaller torque values, common in precision applications. Kilogram-force meter (kgf·m): A metric unit still used in some countries and industries. Kilogram-force centimeter (kgf·cm): Used for smaller torque measurements, common in robotics and small motors. Dyne centimeter (dyn·cm): A CGS unit used in scientific applications for very small torque values. Ounce-force inch (ozf·in): Used for very small torque measurements in precision instruments. Ounce-force foot (ozf·ft): Similar to ozf·in but using feet as the distance unit.
How do I convert Newton-meters to Pound-feet?
To convert from Newton-meters to Pound-feet, multiply by 0.737562. Formula: lbf·ft = N·m × 0.737562. Conversely, to convert from Pound-feet to Newton-meters, multiply by 1.35582. Formula: N·m = lbf·ft × 1.35582. Our converter handles all these calculations automatically.
What is the relationship between N·m and kgf·m?
1 kgf·m = 9.80665 N·m (approximately). This relationship comes from the definition of kilogram-force, which is the force exerted by one kilogram of mass under standard gravity (9.80665 m/s²). Therefore, 1 N·m ≈ 0.10197 kgf·m.
How precise are the conversions?
Our converter uses high-precision mathematical constants and displays results with up to 10 decimal places. For engineering applications, typically 2-4 decimal places are sufficient. You can round the results according to your specific requirements.
Where is torque commonly used?
Torque specifications are critical in many fields: Automotive: Engine torque output, bolt tightening specifications, wheel lug nut torque. Manufacturing: Assembly line torque requirements for fasteners and components. Robotics: Motor torque calculations for joint actuators. Construction: Structural bolt torque specifications. Aerospace: Critical torque values for aircraft components and engines.
What is the difference between torque and moment?
While often used interchangeably, torque specifically refers to a rotational force that causes angular acceleration, while moment is a broader term that can refer to any force applied at a distance from a point. In practice, torque is a specific type of moment that causes rotation.
