(Any unit of length) x (any unit of force) is a perfectly good unit of torque.
You may need to use a few conversion factors if you want it to work together with
anybody else's normal system of units, but it definitely has dimensions of torque.
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
The moment of a force is the multiple of the force and the distance from the point of application. An example is in tightening wheel nuts. The torque spanner used has a calibration in ft.lb or Newton.meters, so that the correct tightening torque is applied. If the shaft was made twice as long, the necessary force at the shaft end would be half as much. The concept of energy E= fd = -f.d + fxd where f is vector force and d is vector displacement. Energy is a quaternion consisting of a real and three vectors.Work is the real moment of force w= -f.d and Torque is the vector moment of force t=fxd.
Torque= length x force. Lenght is the distance to an object. Force must be perpendicularly acting on the object. In your question, you did not specify neither force and length of the knob. So I cannot give you a torque value. I believe the SI unit for torque is "Nm", assuming that you calculated your torque using all SI units. Then you have to convert Nm to pounds.
The rotational equivalent of a force is a torque. Note, however, that a torque is no longer a force - it is a force multiplied by a distance.
Gravitational pull is a force and is measured in Newtons, the unit of force.
The metric unit force of an object is N ( newton). the tool used to measure the force of an object are force gauges ,torque gauges ,force testers.
Joule , the energy unit is the unit for Torque. Torque is vector energy.AnswerThe SI unit for torque is the newton metre(N.m). This should not be confused with the joule (which is a special name for a newton metre), the SI unit for work.With torque, the force (in newtons) acts at right angles to a radius (in metres) to produce a turning moment. With work, the force (in newtons) acts in the same direction as distance travelled (in metres).To calculate the work done by a given torque, it's necessary to multiply the force by the circumference through which the force acts.

the unit of torque is NM.Torque has dimensions of force times distance. Official SI literature suggests using the unit newton metre (N·m) or the unit joule per radian.[8] The unit newton metre is properly denoted N·m or N m.Torque, moment or moment of force is the tendency of a force to rotate an object about an axis.The magnitude of torque depends on three quantities: the force applied, the length of the lever arm[2] connecting the axis to the point of force application, and the angle between the force vector and the lever arm. In symbols:whereτ is the torque vector and τ is the magnitude of the torque,r is the displacement vector (a vector from the point from which torque is measured to the point where force is applied), and r is the length (or magnitude) of the lever arm vector,F is the force vector, and F is the magnitude of the force,× denotes the cross product,θ is the angle between the force vector and the lever arm vector.
Torque is measured as a unit of length times a unit of force, so the SI unit is Newton-meters (Newton times meters). Imperial units would probably be something like foot-pound. Note that this is unrelated to energy units, also measured in Newton-meters. The unit "joule" as an equivalent for Newton-meters is only used for energy units, not for torque units.
what is the unit used in expressing any force
The turning effect of a force is called torque or moment of the force. SI unit of torque is Newton-Metre. T = FL i.e Torque = Force x Moment arm A couple is formed by two unlike parallel forces of the same magnitude but not along the same line.
Since torque is a force, and as such has a direction, it is a vector.
The moment of a force is the multiple of the force and the distance from the point of application. An example is in tightening wheel nuts. The torque spanner used has a calibration in ft.lb or Newton.meters, so that the correct tightening torque is applied. If the shaft was made twice as long, the necessary force at the shaft end would be half as much. The concept of energy E= fd = -f.d + fxd where f is vector force and d is vector displacement. Energy is a quaternion consisting of a real and three vectors.Work is the real moment of force w= -f.d and Torque is the vector moment of force t=fxd.
Before torque wrenches you simply had to judge the amount of force you used by the 'pull' you exerted on the wrench.

It's a newton-metre, folks. A newton meter or N·m is the SI measurement of torque. Another measurement of torque is pounds foot of torque. A newton meter can also be a measurement of energy, and is the energy required to lift a one Newton weight one meter against earth's gravity that is to say above the ground. This means that a newton meter has exactly the same energy as a Joule.
