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.
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.
pounds of force Foot pounds or torque. Measured with a torque wrench.
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.
Assuming a graviational constant of g=9.81 N/kg, you would convert this mass into a weight of mg = 10.5 kg x 9.81 N/kg = 103.005 Newtons and convert it to pounds force (lbf) by the conversion value of 1 N = 0.2248 lbf. Therefore, 103.005 N x 0.2248 lbf/N = 23.16 lbf, or 23.16 lbs It weighs 23.16 pounds, give or take 0.01 pounds due to rounding error.
foot/second.square
The unit for measure for force in the metric system is the Newton (kilogram-metre per second2), however for the English system it is the pound-force (lbf or lbf), which may be called a foot-pound.
pound-force per feet2 (lbf/ft2)
1 kilonewton (kN) is equal to approximately 0.22480894 pounds-force (lbf).
lbs is an abbreviation already, and doesn't get abbreviated further; it is max abbreviated. It stands for the unit of weight 'pound'.
Lift lbf = (Normal force lbf) x (cosine of angle of attack)
The SI-unit for force is the newton (N): 1 N ≡ 1 kg·m/s²= 105 dyn ≈ 0.10197 kp ≈ 0.22481 lbf ≈ 7.2330 pdl.
The pound per square inch or, more accurately, pound-force per square inch (symbol: psior lbf/in2or lbf/in2or lbf/sq in or lbf/sq in) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch:
The unit for measure for force in the metric system is the Newton (kilogram-metre per second2), however for the English system it is the pound-force (lbf or lbf), which may be called a foot-pound.
