During his experiments, Abū al-Rayhān al-Bīrūnī (973-1048) invented the conical measure, in order to find the ratio between the weight of a substance in air and the weight of water displaced, and to accurately measure the specific weights of the gemstones and their corresponding metals, which are very close to modern measurements.
