140 Nm = 103.26 ft-lbs
That is 103.26 lb-ft, 1,239.1 in-lb or 1,427.6 kg-cm.
Some larger cars, SUVs and vans specify around 140 to 160 Nm for wheel nuts. It is close to the typical dry torque for M12 grade 10.9 (126 Nm), M12 grade 12.9 (147 Nm), M14 grade 8.8 (140 Nm). See the metric bolt torque chart. Always use the figure in your vehicle or part maker's manual.
Multiply Nm by 0.737562: 140 x 0.737562 = 103.26 ft-lbs. To go back, multiply ft-lbs by 1.35582. On a torque wrench, set 103 ft-lbs.
