<Li> The effect of atmospheric buoyancy is excluded in the weight . </Li> <Li> In common parlance, the name "weight" continues to be used where "mass" is meant, but this practice is deprecated . </Li> <P> The definition is dependent on the chosen frame of reference . When the chosen frame is co-moving with the object in question then this definition precisely agrees with the operational definition . If the specified frame is the surface of the Earth, the weight according to the ISO and gravitational definitions differ only by the centrifugal effects due to the rotation of the Earth . </P> <P> In many real world situations the act of weighing may produce a result that differs from the ideal value provided by the definition used . This is usually referred to as the apparent weight of the object . A common example of this is the effect of buoyancy, when an object is immersed in a fluid the displacement of the fluid will cause an upward force on the object, making it appear lighter when weighed on a scale . The apparent weight may be similarly affected by levitation and mechanical suspension . When the gravitational definition of weight is used, the operational weight measured by an accelerating scale is often also referred to as the apparent weight . </P>
