IEEE Transactions on Ultrasonics, Ferroelectrics, and Frequency Control 47(2), 317–332 (2000) (Invited paper), Washabaugh, P.D., Peters, K.J. The range of forces covered is from approximately 10-3 to 109 newtons, and those forces may be static or dynamic and single or multi-axis. The basic idea of this method is to use the uncertainty ranges of each variable to calculate the maximum and minimum values of the function. The SI unit of force is the newton (N); defined as the unit of force which would give to a mass of one kilogram an acceleration of 1 meter per second squared.

Force is a vector quantity, with both direction and magnitude. However, kgf (kilogram force), lbf (pound force), and ozf (ounce-force) are also used in other countries. Cite as. Measurement is the numerical quantitation of the attributes of an object or event, which can be used to compare with other objects or events. However, kgf・m and lbf・in are also used in other countries. In a direct comparison method, an unknown force is directly compared with gravitational force acting on a known mass.
