Yes, you can still torque up little things with a big wrench. There are
12 inch-pounds in one foot-pound.
Torque is a twisting force- something has to rotate. You apply a force
some distance away from the turning point, and that's applying torque.
For those who like vector math, the formula is t = F x d, where t is
torque, F is force applied (in this case, pounds) and d is the distance
from the rotation (inches / feet). Metric equivalent is a Newton-Meter.
