Question Gear heads- ft/lb-in/lb conversion question

I need to torque bolts on tranny accumlator to 80-100 in/lbs but only have a foot lbs torque wrench.

Does anyone know how to convert or tell me the foot lbs?

Thanks!

There are 12" in a foot.......

So 80 inch pounds would be 6.6 ft lbs
and 100 inch lbs would be 8.3 ft lbs.

I thought there would be some type of conversion factor.

The conversion factor is:

Inches to feet: divide the number by 12. For instance, the truck bed on the Lightning is wide enough to hold a sheet of plywood which is 48 inches wide. If you want to convert that to feet, divide it by 12 or multiply it by 1/12 (48 inches x 1 ft/12 inches) and you get 4 feet.

Feet to inches: multiply the number by 12. Using the example above, if the plywood is 4 ft wide, it's 4 ft x 12 inches/ft = 48 inches.

Using your example:

84 in-lbs x 1 ft/12in = 7 ft-lbs (you're just dividing by 12)

96 in-lb x 1 ft/12in = 8 ft-lbs

It would be better to have the inch-lb torque wrench because of the precision (not accuracy) of the dial.

1 Inch-Pounds = 0.083333 Foot-Pounds
1 Foot-Pounds = 12 Inch-Pounds
