How much is half a Saa' of wheat, dates, or rice to feed sixty needy people at present, in kilograms or equivalent measures?

The Prophetic Sa' (الصاع النبوي) equals four Mudds (أمداد). One Mudd (المد) is a handful with two moderate, full hands. Estimating the Sa' by weight varies depending on the type of food being measured, so the relied-upon method is by volume (كيل) not by weight. Some scholars have estimated a Sa' of wheat or rice to be approximately three kilograms.
