|Rav Chaim Noeh<ref>Rav Chaim Noeh in Shiurei Torah (3:11, pg 191, 5707) writes that for Deoritta Mitzvot one should eat 28.8cc, however, in Shiurei Tzion (p. 70, 5709) he writes that it is 27cc. Vezot HaBracha (Birur Halacha 1) explains that Rav Chaim Noeh retracted from his original ruling.</ref> | |Rav Chaim Noeh<ref>Rav Chaim Noeh in [https://www.hebrewbooks.org/pdfpager.aspx?req=20888&st=&pgnum=270 Shiurei Torah (3:11, pg 191, 5707)] writes that for Deoritta Mitzvot one should eat 28.8cc, however, in [https://www.hebrewbooks.org/pdfpager.aspx?req=35168&st=&pgnum=69 Shiurei Tzion (p. 70, 5709)] he writes that it is 27cc.

|Chazon Ish<ref>Steipler in Shiurin Shel Torah (second edition, 5750, pp. 65-6; first edition, 5716, pp. 86-7) quotes the Chazon Ish that a [[Kezayit]] is 2/3 of a modern egg and an egg today measures between 45-50 grams. At most, the kezayit would be 33.3 grams. Vezot HaBracha (Birur Halacha 1:3) records this opinion of the Chazon Ish as 33.3cc for a [[Kezayit]]. The Chazon Ish's opinion of [[Kezayit]] is partially based on the opinion of the Tzlach who doubles today's eggs to figure out a kebaytzeh. However, the Chazon Ish also holds that the kezayit is only 1/3 of a kebeytzeh like the Rambam.</ref> | |Chazon Ish<ref>Steipler in Shiurin Shel Torah (second edition, 5750, pp. 65-6; first edition, 5716, pp. 86-7) quotes the Chazon Ish that a [[Kezayit]] is 2/3 of a modern egg and an egg today measures between 45-50 grams.
