Multiply the foot-pound value by 12. For example, 7.5 ft-lb × 12 = 90 in-lb.
Inch-pounds are preferred for smaller torque values, such as tightening screws on electronics, firearms, bicycle components, and small engine parts where foot-pounds would give inconveniently small decimals.
Automotive lug nuts typically require 80-100 ft-lb (960-1200 in-lb), while smaller bolts like valve cover bolts may need just 3-5 ft-lb (36-60 in-lb).
