Newton-meters (Nm) and foot-pounds (ft/lbs) are the metric and imperial measures for torque, which measures the way in which a force turns an object around an axis.
One foot-pound (ft/lb) is equal to 1.356 newton-meters (Nm). To convert newton-meters (Nm) to foot-pounds (ft/lbs) all you need to do is divide your figure (Nm) by 1.356.
Thank you but after some effort I realize I’m denser than I thought. On the first drawing I’m deducing that the range is from the smaller number 1- 0.5 = 0.5 to the larger number 1+ 0.5 = 1.5Nm and the second part is between 9-4=5 foot pounds to 9+4=13 foot pounds.
If I apply the same formula to the second drawing it would read 0.55-0.15=0.40inch foot pounds to 0.55+0.15=0.70 inch foot pounds but that doesn’t match your reading of 1.5 to 2 inch pounds and between 13 to 17 inch pounds. Where am I making my mistake?
