1 newton-meter is equal to 0.7376 ft-lbs, rounded to 4 decimal places. To convert newton-meters to foot-pounds, simply multiply your figure by 0.7376.

The conversion chart below can be used to convert some of the most common torque figures for newton-meters (Nm) and foot-pounds (ft-lb).
Usually, heavy vehicles like trucks, SUVs, as well as industrial machinery, require higher torque.
Overtightening these small fasteners will damage or break the threads, parts connected to the fasteners, and can wear the fastener itself. An inch-pound wrench prevents such an issue from happening.
If you set the torque within the recommended percentage of the wrench’s capability, it should click whenever you apply the exact torque value.
To make it easier for you, I have made a list of top 5 inch-pound wrenches, describing what they are good at and their flaws with a definitive buying guide.
However, the accuracy is slightly less in a counterclockwise direction. Adjusting torque on this wrench is relatively easier and straightforward. here
After you apply the exact amount of torque, you will hear and feel a clicky feedback. The manufacturer assures you about its calibration till it reaches 5,000 cycles or one year of usage. here
In the rest of the world, this unit of torque is usually called a pound foot. In SI the unit of torque is the newton meter, with the name of the unit of force first and of distance second. The pound foot follows that pattern. More correctly, since we are really not dealing in pounds, a unit of mass, but in pound-force's, engineers call the auto mechanics' foot pound a pound-force foot.

In everyday speech in the United States, the foot pound is a unit of torque used, for example, in expressing how strongly to tighten a nut or bolt. Essentially, a manufacturer who specifies that a certain nut be tightened to 1 foot pound of torque is calling for turning the nut by applying a force of 1 pound to the wrench, at a right angle to the wrench, at 1 foot from the axis of the bolt. The inch pound and inch ounce are similarly conceived.

Moving onto another example using the inch pounds torque wrench. Again this is the same principle, this too has a lock which needed to be pulled back, rotate the handle to the correctly value, and then release which will automatically lock into place. For this each of the bolts need to be torques to 20 foot pounds. The inch pound torque wrench does not read in foot pounds, so a simple conversion is needed. 1 foot is equal to 12 inches, therefore 20 multiplied by 12 is 240. Just as an example I will set this to 230 inch pounds, therefore the 0 will need to be aligned on the handled. When setting the torque valve to 240 inch pound, therefore we will need to be past the 230 mark and align the handle to the 10th increment. Place on hand on the pivot point and the other on the handle, then rotate until you hear the click, again only one click is needed. When done with the torque wrench, position the scale back in it’s lowest position. Otherwise this will jeopardize the accuracy of the torque values. [links]
Video tutorial on how to use a torque wrench. There are a few different styles of torque wrenches, but for this video I will be using a click type which is probably the most common. Other types include a beam type, dial, digital, slipper, and, no hub. In the video, I have both an inch pounds torque wrench and foot pounds torque wrench. Both also have readings on the opposite side of newton meters too. Torque wrenches are available in certain torque spans which is why you may need more than one. Here I have a 3/8” drive inch pound torque wrench that goes from 50 to 250 inch pounds. Inch pounds are a finer increment than foot pounds. Next I have a 1/2” drive foot pound torque wrench that has a range of 30 to 150 foot pounds. A torque wrench is a very precise piece of equipment, therefore four tips you should know about ownership is never drop them, do not use them as a johnson bar to loosening tight fasteners, always keep them clean, and return the scale to it’s lowest torque range.
