Matzos are far more consistent in weight per volume than in shape.
Handmade shemurah is around .55g/cc for hand matzos, and up to .58g/cc
for machine.

It therefor becomes more accurate to measure volume using weight than
trying to do so directly.

(The above numbers are from R' Hirsch Meisels, in Going Forward, an
English, Yiddish and Hebrew periodical dealing with issues for O
diabetics. RHM found us shortly after Shuby was diagnosed. I never
found out how. An annual topic: How meikil can/must one be WRT
matzah?)

BTW, my father heard RMWillig say this past Sun that 1/5 of a hand
matzah is sufficient to cover so many chumros that it's arguably
enough for 2 kezeisim (for those who add that yet-another-chumrah).

Also, his revi'is was 2.7oz!

SheTir'u baTov!
