Understanding Torque Conversion: Nm to in-lbs
Torque is a measure of rotational force, and it’s crucial for properly tightening fasteners, assembling machinery, and ensuring mechanical integrity. Newton-meters are the standard metric unit, while inch-pounds are commonly used in the United States and for precision applications.
The Conversion Formula
in-lbs = Nm × 8.85074579
Or inversely:
Nm = in-lbs ÷ 8.85074579
Or inversely:
Nm = in-lbs ÷ 8.85074579
Why This Conversion Factor?
The conversion factor 8.85074579 comes from the relationship between meters and inches, combined with the relationship between Newtons and pounds-force. One Newton-meter equals approximately 8.851 inch-pounds, making this the precise multiplier for accurate torque conversions between metric and imperial systems.
Torque vs Force: Understanding the Difference
While force is measured in Newtons or pounds, torque combines force with distance (the length of the lever arm). Newton-meters multiply force by distance in the metric system, while inch-pounds do the same in the imperial system. This is why proper conversion is critical for mechanical applications.
Importance in Mechanical Work
Correct torque application prevents both under-tightening (which can lead to loose fasteners and failures) and over-tightening (which can damage threads, strip bolts, or crack components). Using the right torque units and values is essential for safety, reliability, and warranty compliance.

Frequently Asked Questions
Q: What is the conversion factor from Nm to in-lbs?
A: The precise conversion factor is 8.85074579. To convert Newton-meters to inch-pounds, multiply the Nm value by 8.85074579. For example, 10 Nm × 8.85074579 = 88.51 in-lbs.
Q: How do I convert 50 Nm to in-lbs?
A: To convert 50 Nm to inch-pounds, multiply 50 by 8.85074579, which equals 442.54 in-lbs. Simply enter 50 in our converter to get this result instantly.
Q: Is Nm the same as in-lbs?
A: No, they are different units for measuring torque. Newton-meters (Nm) is the metric unit, while inch-pounds (in-lbs) is the imperial unit. One Nm equals approximately 8.85 in-lbs, making Nm the larger unit.
Q: What’s the difference between in-lbs and ft-lbs?
A: Inch-pounds and foot-pounds are both imperial torque units, but foot-pounds (ft-lbs) is 12 times larger because there are 12 inches in a foot. To convert in-lbs to ft-lbs, divide by 12. For example, 120 in-lbs equals 10 ft-lbs.
Q: Can I use this converter for torque wrench settings?
A: Yes! This converter is perfect for setting torque wrenches. If your wrench is calibrated in in-lbs but your specifications are in Nm (or vice versa), use this tool to convert the values accurately before beginning your work.
Q: Why is torque conversion important?
A: Proper torque is critical for mechanical integrity and safety. Under-tightening can cause parts to loosen and fail, while over-tightening can strip threads, crack components, or damage sensitive parts. Using the correct units ensures you apply the right force.
Q: Which torque unit should I use?
A: Use the unit that matches your torque wrench calibration and your specification manual. Most international specifications use Nm, while many US-based specifications use in-lbs or ft-lbs. Always convert to match your equipment for accurate results.
