Torque Converter

135 newton-meters equals approximately 99.6 foot-pounds. Most passenger car lug nuts require 80-120 ft-lbs (108-163 N·m). Always check your vehicle manual for the exact specification.

To convert newton-meters to foot-pounds, multiply by 0.7376. For example, 100 N·m equals approximately 73.76 ft-lbs. Many torque wrenches show both scales, but it is important to double-check which unit your specification uses.

There are exactly 12 inch-pounds in 1 foot-pound. Inch-pounds are used for smaller fasteners like spark plugs (typically 12-18 ft-lbs or 144-216 in-lbs) and precision assemblies. Foot-pounds are used for larger fasteners like lug nuts and bolts.

Most passenger cars require lug nut torque of 108-163 N·m (80-120 ft-lbs). SUVs and trucks may need 135-200 N·m. Always consult your vehicle manual - over-torquing can warp brake rotors and under-torquing can cause wheel loss.

One kilogram-force meter (kgf·m) equals 9.80665 N·m or approximately 7.233 ft-lbs. It appears in older machinery specifications, Japanese vehicle manuals and some industrial equipment. Modern standards prefer newton-meters.
