Torque Units Conversion: A Comprehensive Guide for Torque Enthusiasts

Introduction

Torque, a physical quantity that measures the rotational force applied to an object, is a crucial concept in various industries, from automotive engineering to industrial machinery. Understanding torque units and their conversions is essential for accurate calculations and effective communication in these fields. This article provides a comprehensive guide to torque units conversion, empowering you with the knowledge to navigate the complexities of torque measurements.

Torque Units: A Global Perspective

Torque is typically measured in newton-meters (N·m) or foot-pounds (lb-ft). These two units dominate the global torque landscape, with N·m being the preferred unit in the International System of Units (SI) and lb-ft remaining popular in the United States and other imperial-based countries.

Conversion Factor: Bridging the Gap

The conversion factor between N·m and lb-ft is 0.738:
