How do you convert transformer oil from liters to kilograms?

To convert transformer oil from liters to kilograms, you need to know the density of the transformer oil, which is typically around 0.88 to 0.92 kg/L. Use the formula: weight (kg) = volume (L) � density (kg/L). For example, if you have 100 liters of transformer oil with a density of 0.9 kg/L, the conversion would be 100 L � 0.9 kg/L = 90 kg.
