How much does transformer oil weigh?

Transformer oil typically weighs between 0.8 to 0.9 grams per cubic centimeter (g/cm³) at room temperature. This density can vary slightly depending on the specific formulation and additives used in the oil. For practical applications, a common estimate is around 860 to 890 kilograms per cubic meter (kg/m³). Understanding the weight of transformer oil is crucial for calculating the total weight of the transformer and ensuring proper handling and storage.
