For other meanings of the word balance, see:
A balance (also beam balance or laboratory balance) is used to accurately measure the mass of an object. This class of measuring instrument uses a comparison technique in its conventional form of a beam from which a weighing pan and scale pan are suspended. To weigh an object, it is placed on the measuring pan, and standard weights are added to the scale pan until the beam is in equilibrium.
Very precise measurements are achieved by ensuring that the fulcrum of the beam is frictionIn physics, friction is the resistive force that occurs when two surfaces travel along each other when forced together. It causes physical deformation and heat buildup. The frictional force is a function of the force pressing the surfaces together and the-free (a knife edge is the traditional solution), by attaching a pointerThis article is about the computer data type. For other meanings of pointer see pointer (disambiguation). In computer science, a pointer is a programming language datatype whose value is used to refer to ("points to") another value stored elsewhere in the to the beam which amplifies any deviationIn radio, frequency deviation is the result of frequency modulation. In the FM band for broadcasting, deviation is normally 150 kHz total, which is ±75kHz of the carrier frequency. Excessive deviation is the result of overmodulation, and causes interferen from a balance position; and finally by using the leverIn physics, a lever is a rigid object that is used with an appropriate fulcrum or pivot point to multiply the mechanical force that can be applied to another object. This is also termed mechanical advantage, and is one example of the principle of moments. principle, which allows fractionIn common usage a fraction is any part of a unit. In mathematics: A vulgar fraction is a rational number written as one integer (the numerator divided by a non-zero integer (the denominator . The line that separates the numerator and the denominator is caal weights to be applied by movementThe term Movement has a variety of different meanings: Physical movement between points in space ("A to B"). The amount of movement is called distance. Together with a direction you have a displacement. The rate of movement is the speed. Again, with the d of a small weight along the measuring arm of the beam.
While the word "weigh" or "weight" is often used, any balance scale actually measures mass, which is not dependent upon the forceIn physics, a net force acting on a body causes that body to accelerate; that is, to change its velocity. The concept appeared first in the second law of motion of classical mechanics. It is usually expressed by the equation F m · a where F is the force, of gravity, as opposed to a scale with a spring, which measures weight. Mass is properly measured in grams, kilograms, pounds, ounces, or slugs; while weight is in newtons or pound force.

In banking and accountancy, the outstanding balance is the amount of money owned, (or due), that remains in a deposit account (or a loan account) at a given date, after all past remittances, payments and withdrawal have been accounted for. It can be positive (then, in the balance sheet of a firm, it is an asset) or negative (a liability).
Balance can also refer to the amount of signal from each channel reproduced in a stereo recording.
