What It Does

A Torque Converter is a specialized tool for converting between different units of torque (rotational force) measurement. Torque is the rotational equivalent of linear force, causing objects to rotate around an axis. The converter converts between metric units like newton-meters (N·m) and kilonewton-meters (kN·m), imperial units like foot-pounds (ft·lb) and inch-pounds (in·lb), and gravitational units like kilogram-meters (kgf·m). This tool is essential for automotive work (engine torque, bolt tightening), mechanical engineering (motor specifications, rotational systems), construction (torque wrenches), and scientific applications. It provides accurate conversions with high precision, supporting both metric (SI) and imperial systems. Perfect for understanding engine torque ratings, bolt torque specifications, motor ratings, and any rotational force measurements.

Frequently Asked Questions

1 What is torque and how is it different from force?
Torque is rotational force - it causes objects to rotate around an axis, while linear force causes objects to move in a straight line. Torque is measured as force × distance from the rotation axis. For example, applying 10 newtons of force at 1 meter from the pivot creates 10 newton-meters of torque. Torque units combine force and distance: newton-meters (N·m), foot-pounds (ft·lb), etc. This is why torque has different units than force - it includes both force and distance components.
2 How do I convert foot-pounds to newton-meters?
To convert foot-pounds to newton-meters, multiply by 1.35582. For example, 100 ft·lb × 1.35582 = 135.58 N·m. To convert newton-meters to foot-pounds, multiply by 0.737562. For example, 100 N·m × 0.737562 = 73.76 ft·lb. Foot-pounds are commonly used in the US for automotive torque, while newton-meters are standard in Europe and scientific applications.
3 What is the difference between foot-pounds and inch-pounds?
Foot-pounds and inch-pounds are both imperial torque units, differing only in the distance component. One foot-pound equals 12 inch-pounds (since 1 foot = 12 inches). For example, 100 ft·lb = 1,200 in·lb. Inch-pounds are used for smaller torque values (like small screws, electronics), while foot-pounds are used for larger values (like automotive bolts, engines). The converter handles both units and their conversions.
4 Why are torque specifications important?
Torque specifications ensure fasteners are tightened correctly: too loose and they may come undone, too tight and they may break or strip threads. Proper torque prevents equipment failure, ensures safety, and maintains warranty coverage. Different applications require different torque values based on fastener size, material, and application. Always follow manufacturer torque specifications and use a calibrated torque wrench for critical applications.
5 What torque unit should I use?
Use the unit that matches your torque wrench or specification manual. US automotive work typically uses foot-pounds or inch-pounds. European automotive work uses newton-meters. Scientific and engineering applications use newton-meters (SI unit). Small precision work may use inch-pounds or gram-centimeters. The converter helps you work with any unit system and convert to match your tools or requirements.
6 Can I convert very small torque values?
Yes, the converter handles very small torque values using gram-centimeters or dyne-centimeters. For example, 1 gram-centimeter = 0.0000980665 newton-meters. These small units are used for precision applications like electronics, small motors, and delicate mechanisms. The converter provides high precision (up to 6 decimal places) to handle both large (engine torque) and small (precision mechanisms) values accurately.
