Introduction

Torque plays a vital role in engineering, mechanics, physics, and everyday applications like vehicles, machines, and tools. But torque values aren’t always expressed in the same unit. For example, one source may use Newton-meters (Nm), while another prefers foot-pounds (ft-lb) or kilogram-force meters (kgf·m). Converting between these units can be tricky if done manually.

That’s where the Torque Conversion Calculator comes in. This tool simplifies the entire process by instantly converting between different torque units. Whether you’re an engineer working with motors, a student studying physics, or a mechanic analyzing tools and engines, this calculator ensures accuracy and saves time.

The Torque Unit Converter covers all major units used globally, allowing seamless conversion across systems like SI (metric) and Imperial. With just a few clicks, you can convert values such as Nm to ft-lb, kgf·cm to Nm, or lbf·in to Nm.

How to Use Torque Conversion Calculator

Using the Torque Conversion Calculator is simple:

  1. Enter Torque Value
    Input the torque value you want to convert. For example: 100 Nm.

  2. Select Input Unit
    Choose the unit of the entered torque. Options include:

    • Newton-meters (Nm)

    • Foot-pounds (ft-lb)

    • Inch-pounds (in-lb)

    • Kilogram-force meters (kgf·m)

    • Gram-force centimeters (gf·cm)

  3. Choose Output Unit
    Select the unit you want to convert into.

  4. Click Convert
    Instantly view the result displayed in the chosen output unit.

  5. Optional Multi-Conversion
    Some calculators also show values converted into all major torque units simultaneously, saving you extra effort.

Common Torque Units Explained

Here are the most widely used torque units you’ll encounter:

  • Newton-meter (Nm): The SI unit of torque, used internationally in engineering and physics.

  • Foot-pound (ft-lb): Commonly used in the United States, especially in automotive and mechanical contexts.

  • Inch-pound (in-lb): Another U.S. unit, often used for smaller torque values like screws and bolts.

  • Kilogram-force meter (kgf·m): A metric unit used in some regions, especially in older engineering references.

  • Gram-force centimeter (gf·cm): Useful for precise torque measurement in small instruments.

Conversion Table for Torque Units

To give you a quick reference, here’s a table showing conversions between common torque units:

From / To 1 Nm equals 1 ft-lb equals 1 in-lb equals 1 kgf·m equals
Newton-meter (Nm) 1 Nm = 0.7376 ft-lb 1 Nm = 8.8507 in-lb 1 Nm = 0.10197 kgf·m
Foot-pound (ft-lb) 1 ft-lb = 1.3558 Nm 1 ft-lb = 12 in-lb 1 ft-lb = 0.13825 kgf·m
Inch-pound (in-lb) 1 in-lb = 0.113 Nm 1 in-lb = 0.0833 ft-lb 1 in-lb = 0.01152 kgf·m
Kilogram-force meter (kgf·m) 1 kgf·m = 9.8067 Nm 1 kgf·m = 7.233 ft-lb 1 kgf·m = 86.796 in-lb

Benefits of Using Torque Conversion Calculator

The Torque Conversion Calculator offers multiple benefits:

  • Accuracy – Removes human error from manual calculations.

  • Saves Time – Converts instantly without needing formulas.

  • Covers All Major Units – Works with SI, Imperial, and metric systems.

  • Useful for Professionals – Engineers, mechanics, and physicists rely on quick torque conversions.

  • Student-Friendly – Perfect for physics and engineering assignments.

  • Global Compatibility – Handles conversions between units used in different countries.

Why Torque Conversion Matters

Torque values differ across industries and regions. Here’s why conversion is essential:

  • Automotive Industry: Car manuals in the U.S. often use ft-lb, while international standards use Nm. Mechanics must convert between these.

  • Engineering Applications: Machine specifications may list torque in kgf·m or Nm, requiring accurate conversion for design and testing.

  • Physics and Education: Students need to convert between torque units for problem-solving.

  • Tool Usage: Wrench settings may be in in-lb or Nm, depending on the manufacturer.

Tips & Best Practices

  • Always confirm the unit of torque before applying it to avoid errors.

  • Use the Power Torque Speed Conversion Calculator (linked internally) when you need relationships between torque, speed, and power.

  • Double-check values when working with high-torque machinery, as even small errors can cause mechanical damage.

  • Keep a copy of conversion tables handy for quick offline reference.

  • Prefer SI units (Nm) in academic and professional settings for consistency.

Advanced Topic: Power, Torque, and Speed

Torque doesn’t exist in isolation—it connects with power and rotational speed. The formula is:

Power (W) = Torque (Nm) × Angular Speed (rad/s)

For practical applications, especially motors and engines:

Horsepower (HP) = (Torque (ft-lb) × RPM) ÷ 5252

This is why RaikTools also provides a Power Torque Speed Conversion Calculator—to help you go beyond simple unit conversions and understand real-world performance.

Faqs
