A good understanding of the material budget of the ATLAS Inner Detector is crucial for physics analyses at ATLAS. This note describes three complementary studies of the material located inside of the ATLAS electromagnetic calorimeter, using converted photons, uniformity of the energy flow in the electromagnetic calorimeter, and reconstructed $K_S$ mass variations.
