My repair manual quotes some specs in inch pounds (in-lbs) as opposed to foot pounds. How do I convert?j?

Question

My torque wrench does not read in "in-lbs". What for example is 150 in-lbs in foot pounds? My stablizer bar link nut torque spec is said to be 150 in-lbs. Why is it necessary to quote torque specs in both inch and foot lbs? How do I convert one to the other. Thanks much in advance. Jim Confused

Answer 1

They spec in inch-pounds for a couple of reasons.
1) The foot pound spec is extremely low.
2) Greater potential for over-torqueing if foot-pound specs are used.
The conversion is to divide your inch pounds by 12. Which means your torque wrench will be set to 12.5 foot pounds. Not much torque. You are best off purchasing a torque wrench that reads in inch-pounds. An inch-pound torque wrench is shorter in length than a foot-pound torque wrench since you won't need nearly as much torque to tighten the bolt or nut.

Answer 2

Since there are 12 inches in 1 foot, simply divide 150 by 12, and that will give you the answer in foot-pounds, as well as your answer as to why it is necessary to express specs. in both inch-pounds and foot-pounds. Hope this helps.

Answer 3

whats posted above is correct. you will also need to buy different torque wrenches for different torque levels. i have a whole drawer in my toolbox of just torque wrenches, about 10. a torque wrench is not accurate on the far edges of its torque value.

Answer 4

It's 12.5 ft lbs
