Rabbi Meir says

all the cubits [mentioned with regard to the Temple]

were the medium cubits (of six handbreadths, as opposed to five, which was the case with the following excptions),

except for the Altar of Gold,

and the horns [of the larger altar in the courtyard],

and the ledge [of the larger altar in the courtyard],

and the base [of the larger altar in the courtyard];

Rabbi Yehuda says

the cubit of the structure [of the Temple]

was six handbreadths,

and of [the Temple's] utensils

was five.

פרק יז משנה יא

And there are those [measures] in with they spoke

in small measures (rather than medium or large):

Measures of liquid and dry [volumes used in the Temple],

their measures are in the Italian,

which is [the same as] of the wilderness.

And there are those [measures] in with they spoke

all according to the individual:

The [kohen] who performed kemitzah on a korban mincha (in which he would scoop flour using his middle three fingers),

and the [Kohen Gadol] who scoops [with his hand] the incense [on Yom Kippur],

and one who drinks his cheekful

on Yom Kippur (which is the minimum amount to be culpable),

and the food for two meals for a eruv (this refers to the amount of food that must be used to change the starting point of one's techum, the maximum distance that one may travel on shabbos)

(which also is) ones' food for a weekday

but not for shabbos,

this is the opinion of Rabbi Meir;

Rabbi Yehuda says

for shabbos but not for the weekdays.

and this one and that one [Rabbi Meir and Rabbi Yehuda] intended to be lenient (each thought that his measure was the smaller);

Rabbi Shimon says (this measure was)

two thirds of a loaf

of which there are three [loaves] to a kav (a kav is a measure of volume equal to 24 eggs, and so the measure for this eruv is two thirds of one third of that, or five and one third eggs);

Rabbi Yochanan ben Brokah says

a loaf word a pundyon

when four se'ah cost a sela (a pundyon was worth forty-eight sela, so this loaf would be 1/12 of a se'ah).
