Nm To Lbs Calculator
Nm to Lbs Calculator
Convert Newton-meters (Nm) to Pound-force feet (lbs-ft) and other torque units. One Newton-meter equals approximately 0.7376 pound-force feet.
Torque Conversion Results
If you’ve ever read a car manual or torque wrench specification, you’ve probably seen torque values listed in either Newton meters (Nm) or pound-feet (lb-ft). Both units measure the same thing — rotational force — but are used in different regions of the world.
The Nm to Lbs Calculator helps you quickly and accurately convert between these two torque measurements without manual math or conversion charts.
- Newton meter (Nm) → The metric unit of torque used globally.
- Pound-foot (lb-ft) → The imperial unit commonly used in the United States.
This calculator is especially helpful for mechanics, engineers, car enthusiasts, and DIY tuners who work with torque specifications from different systems.
⚙️ The Conversion Formula
The relationship between Newton meters and pound-feet is straightforward:
1 Nm = 0.73756 lb-ft
So, to convert Newton meters to pound-feet, simply multiply by 0.73756.
✅ Example Calculation
Let’s say your car’s manual lists a torque spec of 250 Nm:
250 × 0.73756 = 184.39 lb-ft
That means your engine produces about 184.4 pound-feet of torque.

Just enter your torque value in Newton meters (Nm), and get the result in pound-feet (lb-ft) instantly.
| Nm (Input) | Lb-ft (Output) |
|---|---|
| 10 Nm | 7.38 lb-ft |
| 25 Nm | 18.44 lb-ft |
| 50 Nm | 36.88 lb-ft |
| 100 Nm | 73.76 lb-ft |
| 250 Nm | 184.39 lb-ft |
| 500 Nm | 368.78 lb-ft |

📏 Why Torque Conversion Matters
Understanding torque conversions is critical if you:
- Work on cars, bikes, or heavy machinery 🧰
- Use tools (like torque wrenches) calibrated in lb-ft or Nm
- Tune engines and need exact torque specs ⚡
- Work in engineering, physics, or mechanical design 🧪
Even a small error in torque can cause loose bolts, damaged parts, or safety issues, especially in engines and suspension systems.
🔄 Reverse Conversion — Lbs to Nm
Sometimes, you’ll need to convert torque in the opposite direction — from pound-feet (lb-ft) to Newton meters (Nm).
The reverse formula is:
1 lb-ft = 1.35582 Nm
So:
Torque (Nm) = Torque (lb-ft) × 1.35582
Example:
150 lb-ft × 1.35582 = 203.37 Nm
📊 Quick Reference Conversion Table
| Nm | lb-ft | lb-in |

| 1 | 0.73756 | 8.8507 |
| 5 | 3.6878 | 44.253 |
| 10 | 7.3756 | 88.507 |
| 25 | 18.439 | 221.27 |
| 50 | 36.878 | 442.54 |
| 100 | 73.756 | 885.07 |
| 250 | 184.39 | 2,212.7 |
| 500 | 368.78 | 4,425.3 |

🧠 Real-World Uses
Here’s where torque conversions are used every day:
- Auto mechanics: tightening wheel nuts, head bolts, suspension arms
- Motorcycle maintenance: adjusting clutch and brake components
- Aerospace & engineering: precision assembly with torque standards
- Physics labs: mechanical testing and rotational force measurements
No matter your field, accurate torque conversion ensures safety, reliability, and performance.
🧰 Pro Tip — Avoid Costly Mistakes
When using a torque wrench:
- Always match your wrench unit (Nm or lb-ft) to the manufacturer’s spec.
- Double-check the conversion factor before tightening bolts.
- Avoid rounding too aggressively — even small differences matter!
Example mistake:
If a bolt requires 100 Nm but you set the wrench to 100 lb-ft, you’re applying 35% more torque than required — which can strip threads or snap bolts.
