Cool Torque values

How do you adjust torque to in-lbs.? I have a 3/8 & 1/2" drive torque wrenches and neither have in-lbs. gauge. both have ft.- lbs. and Nm. gauge. Looking for to torque the Derby Cover. Yes, I know this gives me away as either **** or DA but if "they" want 10.8 in.-lbs., how do you get it? Checked several catalogs & no in.-lbs. wrench.

Seems like 1 ft.lb. equals 12 in. lbs.

Oops. Someone beat me to it.

Take the number of foot lbs required and multiply it by one billion...then take the sum of that equation and divide it by 12 billion and you will have your answer.

But for a derby cover I use E=MC2/12653x (08663.4663 x 437)/23661834 = 100 inch lbs

or the Bavarian measurement system: Gutentite

You can find that conversion on the Torque conversion page here:

http://www.onlineconversion.com/torque.htm

To convert foot pounds to inch pounds, multiply by 12.
To convert inch pounds to foot pounds, divide by 12.

If the torque value is a small inch-pound number, consider an inch-pound torque wrench for (IMO) better accuracy.

Default Harbor Freight

Harbor Freight has a IN-LB one on sale for $7.95. It's 3/8 drive. Got one not too long ago. Do the Derby by fill. Snug up snug and go about 1/8" turn. Warm bike on a short ride and re-snug. It's safer since the Al threads can get ragged and even the minimum torque will strip them.
