How to convert foot-pounds to inch-pounds

1 lbf·ft = 12 lbf·in, so multiply by 12 to go from foot-pounds (lbf·ft) to inch-pounds (lbf·in). Going the other way, 1 lbf·in = 0.0833333333333 lbf·ft.

lbf·in = lbf·ft × 12
lbf·ft = lbf·in × 0.0833333333333

Worked example:

1 lbf·ft = 12 lbf·in
5 × 12 = 60 lbf·in
