Asked by Morgan
I have a problem where I need the force exerted by an object onto a scale. The object weighs 22 lbs. What is the force? Do I need to multiply that by 32.2 ft/s^2?
What are the US units for force and what is it in this situation?

If the objects has a mass of 22 lb, it will exert a force on a scale of 22 lb.
When solving equations of mechanics with British units, mass is usually stated in slugs. One slug has a weight of 32.2 pounds, at the Earth's surface.
If you are using the equation F = ma, for example, you cannot use pounds for both force F and mass m.
