Embodiments relate to weighing a bale formed by a round baler. One or more load cells, but not including load cells at each support of the baler, are used to obtain a measurement of the baler containing the bale and a measurement of the baler empty. Factors related to the slope of the surface on which the baler is located, the size of the bale, and the shape of the bale are used to adjust the measured weight of the bale.
