In this paper we present an English summary of al-Risāla al-muhītīyya ("The Treatise on the Circumference"). This treatise is one of the most significant mathematical achievements of Ghiyāth al-Dīn Jamshīd Mas'ūd al-Kāshī which he completed in July 1424 (Sha'bān 827 A.H.L.). Also, we present a complete English translation of the titles of all ten sections as well as the title of the introduction and the title of the conclusion. Additionally, we provide comments throughout the paper as necessary.
