OK, I guess I originally misread your question. You are referring to inch-pounds (torque, I guess). Torque or work or energy is force (times) distance. So the [in lbs] implies that you are talking about pounds-force. With [lbf in], it is just clarifying that it is force.
Many people think of mass and 'weight' interchangably. lbs refers to mass. 2.2 lbs is approximately equal to 1 kilogram mass. lbf refers to force. a 1 pound mass (lb), will exert a 1 pound force (lbf), if there is 1 Earth 'g' of acceleration. (approx 9.8 m/s2 or 32.2 ft/s2). Alternatively, take that 1 kg mass, which 'weighs' 1 Newton. It has a mass of 2.2 lbs, and a 'weight' of 2.2 lbf.

Yes, "pounds" (lbs) is a unit of mass, while "lbf" (pound-force) is a unit of force. They are related by the acceleration due to gravity (9.81 m/s^2), where 1 lbf is approximately equal to 0.4536 kg or 4.448 N.
To convert 200 pounds-force (lbf) to pounds-mass (lbm), we need to divide by the acceleration due to gravity, which is approximately 32.2 ft/s^2. Therefore, 200 lbf is equivalent to about 6.21 lbm.
Pascal is the s.i unit of upthrust
Miles per hour (mph) is a unit of speed, while pounds per square foot (psf) is a unit of pressure. The two units measure different physical quantities and cannot be directly converted from one to the other.
In the metric system, the unit of force is the newton (N), while in the English system, the unit of force is the pound-force (lbf).
"Pound" is a unit of force, whereas "yard" is a unit of length or distance. They have different physical dimensions, and they're used to measure different quantities. Neither one can be converted into the other one. Try and find out how many pounds Bret Favre passed for last year.
