Common torque specifications

Application	Typical torque
Wheel nuts (car)	100–130 Nm
Cylinder head bolts	60–100 Nm
Spark plugs	20–30 Nm
Sump plug (oil drain)	25–35 Nm
Brake caliper bolts	25–35 Nm

Multiply Newton-metres by 0.7376 to get foot-pounds. For example: 100 Nm × 0.7376 = 73.76 ft-lb. To convert the other way, multiply ft-lb by 1.3558 to get Nm. So 100 ft-lb = 135.58 Nm. Use the calculator above for instant conversion in any direction.

Both measure torque but at different scales. 1 ft-lb = 12 in-lb. Foot-pounds are used for larger fasteners like wheel nuts and engine bolts. Inch-pounds are used for smaller, more precise applications like interior trim screws and small engine components. Always check your service manual for the correct unit.

Most passenger car wheel nuts should be torqued to 100–130 Nm (74–96 ft-lb). However, always check the manufacturer specification for your specific vehicle. Alloy wheels and aftermarket wheels may have different requirements. Never guess on safety-critical fasteners — use a calibrated torque wrench.

150 Nm equals 110.63 ft-lb. Use the converter above to check any value instantly — enter 150 in the Nm field and all conversions appear immediately including ft-lb, in-lb, and kg-cm.
