Definition: Initialism of grams per square metre (unit for measuring the weight of paper)
Alright class, settle down and letโs take a look!
Youโve stumbled upon a little code, you see,
A short way to say something โ that's G.S.M., agree?
It stands for
G
rams
P
er
S
quare
M
eter, itโs true,
A measurement of paper, light and new!
Think about a sheet, so thin and neat,
How much weight does it have, bittersweet?
That's what G.S.M. tells us, clear and bright,
A measure of density, shining like a light!
Does anyone want to try a little rhyme?
To help remember this measurementโs prime!
So there you have it โ G.S.M. explained with glee,
Any questions before we move on, you see?
