For example, enter 100 if a specification lists 100 units of torque.<\/li>\n<li>Choose the unit attached to that number in <strong>From unit<\/strong>. The default is newton-meter (N\u00b7m).<\/li>\n<li>Choose the unit you need in <strong>To unit<\/strong>. The default is pound-force foot (lbf\u00b7ft).<\/li>\n<li>Read <strong>Converted Torque<\/strong>, which shows the value and its target unit. Change either unit to make another conversion.<\/li>\n<\/ol>\n<p>Both unit menus offer the same six choices: N\u00b7m, kN\u00b7m, N\u00b7cm, kgf\u00b7m, lbf\u00b7ft, and lbf\u00b7in. Selecting the same unit in both menus leaves the numerical value unchanged.<\/p>\n<h2>What torque means<\/h2>\n<p>Torque describes a force\u2019s tendency to turn an object around an axis. Applying a force farther from the axis generally creates more torque: a long wrench makes it easier to turn a fastener than a short one when the same perpendicular force is applied. Torque is used in fastener specifications, motors, engines, gearboxes, and rotating equipment.<\/p>\n<p>For a force applied at a distance from the rotation axis, torque magnitude is \\(T=rF\\sin\\theta\\), where \\(r\\) is the distance to the point of application, \\(F\\) is force, and \\(\\theta\\) is the angle between the distance and force directions. The converter does not calculate torque from those measurements; it converts an existing torque value between units. If you need to convert a force value first, use the <a href=\"https:\/\/wpcalc.com\/en\/converters\/force\/\">force converter<\/a>.<\/p>\n<p>Newton-meter (N\u00b7m) is the SI unit used for torque. Pound-force foot (lbf\u00b7ft) and pound-force inch (lbf\u00b7in) express torque using force in pounds-force and distance in feet or inches. Kilogram-force meter (kgf\u00b7m) uses kilogram-force, which is not the same as a kilogram of mass. Keep the force and distance parts of each unit together when reading a specification.<\/p>\n<h2>Conversion factors and practical limits<\/h2>\n<p>Each factor below gives the value of one unit in N\u00b7m. To convert to N\u00b7m, multiply by the factor. To convert from N\u00b7m, divide by it. The calculator uses these factors for every unit pair.<\/p>\n<table>\n<thead>\n<tr>\n<th>Unit<\/th>\n<th>1 unit in N\u00b7m<\/th>\n<\/tr>\n<\/thead>\n<tbody>\n<tr>\n<td>Newton-meter (N\u00b7m)<\/td>\n<td>1<\/td>\n<\/tr>\n<tr>\n<td>Kilonewton-meter (kN\u00b7m)<\/td>\n<td>1,000<\/td>\n<\/tr>\n<tr>\n<td>Newton-centimeter (N\u00b7cm)<\/td>\n<td>0.01<\/td>\n<\/tr>\n<tr>\n<td>Kilogram-force meter (kgf\u00b7m)<\/td>\n<td>9.80665<\/td>\n<\/tr>\n<tr>\n<td>Pound-force foot (lbf\u00b7ft)<\/td>\n<td>1.3558179483<\/td>\n<\/tr>\n<tr>\n<td>Pound-force inch (lbf\u00b7in)<\/td>\n<td>0.112984829<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>Check the unit carefully before entering a number. In particular, N\u00b7cm is one-hundredth of an N\u00b7m, while kN\u00b7m is one thousand N\u00b7m. Confusing either with N\u00b7m can produce a substantial error. The menus do not include ounce-force inch, so a value given in that unit needs a separate conversion before it can be entered here.<\/p>\n<p>The input accepts values of zero or greater. The displayed result is rounded to at most 10 decimal places, so very small nonzero results may appear as zero. For critical settings, follow the equipment manufacturer\u2019s stated unit, tolerance, and rounding instructions rather than adding precision implied by a conversion.<\/p>\n<p>Torque is related to rotational motion, but converting its units does not determine how quickly a shaft spins or how it accelerates. For other rotating-system quantities, see the <a href=\"https:\/\/wpcalc.com\/en\/converters\/inertia\/\">moment of inertia converter<\/a> or <a href=\"https:\/\/wpcalc.com\/en\/converters\/frequency\/\">frequency converter<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Convert torque between N\u00b7m, kN\u00b7m, N\u00b7cm, kgf\u00b7m, lbf\u00b7ft, and lbf\u00b7in.
