# If one ate between a third and a half a KeBaytzah one should not make a Bracha achrona because of safek Brachot. Therefore, one should have less than a third and not make a Bracha achrona or more than a half and make a Bracha achrona. <Ref> Mishna Brurah 486:1 </ref> | # If one ate between a third and a half a KeBaytzah one should not make a Bracha achrona because of safek Brachot.

# On מצות Deoritta such as eating Matzah one must be strict to hold a Kezayit is a half a Kebaytzah. However, regarding מצות Derabbanan it’s preferable to hold that a kezayit is a half a kebaytzah, however, one may rely on the opinion that a kezayit is a third a kebaytzah. <Ref> Mishna Brurah 486:1 </ref> | # On מצות Deoritta such as eating Matzah one must be strict to hold a Kezayit is a half a Kebaytzah.

==Prutah== | |||
# A prutah is 1/40 of a gram of silver (which is about a few cents). However, the prutah with regards to the mitzvah of returning a lost object is discussed [[Returning_Lost_Objects#Worth_a_Prutah| here]]. <ref> S”A CM 88:1 says a prutah is a half of a pearl of barley. Shiurei Torah (Rav Chaim Noeh pg 177) and Shiurei HaMitzvot (Chazon Ish pg 65) say a prutah is 1/40 of a gram of silver (which currently is about 2.3 cents). See Halachos of Other People’s Money (Rabbi Bodner pg 150) regarding a prutah for the mitzvah of returning a lost object. </ref> | |||
