Newton Meter Converter
Convert torque between newton-meters (Nm), foot-pounds (ft-lb), and inch-pounds (in-lb) instantly with this free online torque converter. Enter any torque value and select units for accurate results.
About This Calculator
The Newton Meter Converter is a free online tool that instantly converts torque values between newton-meters (Nm), foot-pounds (ft-lb), and inch-pounds (in-lb). Whether you are a mechanic working on automotive repairs, an engineer designing mechanical systems, or a DIY enthusiast assembling furniture, this converter helps you get accurate torque conversions between SI and imperial units.
The conversion uses the standard formula: torque is converted to a base value in newton-meters and then divided by the target unit's conversion factor. One foot-pound equals approximately 1.3558 Nm, and one inch-pound equals approximately 0.112985 Nm. The converter handles all three units in any direction, so you can convert Nm to ft-lb, ft-lb to in-lb, or any other combination.
How to Use
Enter your torque value in the input field, select the source unit from the first dropdown, and choose the target unit from the second dropdown. Click Convert to see the result instantly. The tool supports values with decimal places for precision work.
Regional Notes
United States: Torque is commonly measured in foot-pounds and inch-pounds on US-market tools and in automotive service manuals. Many precision fasteners specify torque in in-lb for smaller components.
India, Europe, and Asia: Newton-meters are the standard SI torque unit used in engineering, automotive manufacturing, and technical specifications. Most vehicle manufacturers specify bolt torque in Nm.
United Kingdom: While the UK officially uses the metric system, some legacy automotive and construction references still use imperial torque units. This converter supports effortless switching between both systems.
Frequently Asked Questions
How do you convert newton-meters to foot-pounds?
To convert newton-meters (Nm) to foot-pounds (ft-lb), divide the Nm value by 1.3558. For example, 100 Nm ÷ 1.3558 = 73.76 ft-lb. This conversion factor comes from the relationship where 1 ft-lb = 1.3558179483 Nm.
How do you convert newton-meters to inch-pounds?
To convert newton-meters (Nm) to inch-pounds (in-lb), divide the Nm value by 0.112985. For example, 10 Nm ÷ 0.112985 = 88.51 in-lb. There are approximately 8.851 inch-pounds in one newton-meter.
What is the difference between foot-pounds and inch-pounds?
One foot-pound (ft-lb) equals 12 inch-pounds (in-lb). Both measure torque, but foot-pounds are more common for automotive and industrial applications while inch-pounds are used for smaller fasteners and precision torque wrenches.
Is torque measured in Nm or ft-lb in different countries?
Newton-meters (Nm) are the standard SI unit for torque used in most countries worldwide including India, Europe, and Asia. Foot-pounds (ft-lb) and inch-pounds (in-lb) are primarily used in the United States and occasionally in the UK for automotive and construction applications.
Can I use this converter for automotive torque specifications?
Yes, this converter is ideal for automotive torque specifications. Many vehicle service manuals provide torque values in Nm, while some US-market tools read in ft-lb. Use this tool to convert between units when following manufacturer specifications for bolts, lug nuts, and engine components.
What tools measure torque in newton-meters?
Torque wrenches, digital torque meters, and torque screwdrivers commonly measure torque in newton-meters. Most automotive, industrial, and precision tools from European and Asian manufacturers use Nm as the primary torque unit.
What is the conversion formula for torque?
Torque conversion uses a simple multiplicative formula. To convert from unit A to unit B, multiply the torque value by the conversion factor: value in B = value in A × (conversion factor of A to the base unit) ÷ (conversion factor of B to the base unit). For Nm as the base, 1 Nm = 1 Nm, 1 ft-lb = 1.3558 Nm, and 1 in-lb = 0.112985 Nm.
