Although the mathematical expression for absolute Bouguer anomaly is explicit and available in correct form in some textbooks, this is not the case of the relative Bouguer anomaly. The formula for relative Bouguer anomaly seems in conflict with the definition of gravity anomaly. This paper presents a mathematical expression for relative Bouguer anomaly that is consistent with the definition of gravity anomaly. In the given expression, both the relative Bouguer anomaly and the absolute Bouguer anomaly reflect density distribution below the gravity stations. This means that given the gravity reading at a base station, the expected gravity reading at a gravity station is calculated by incorporating the corrections to the base station reading. The relative anomaly at the base station is zero.
