liter(L)
also spelled (litre) is the derivedunitfor
VOLUME
Use thesymbolL
So you may ask"what's with a capital letterLfor liter?
Is that a capitalLfor the unit of measure named
after a person like C for Celsius?No....
You see, when decimal dimensions were described
long beforethe typewriter we would have to
write the script.
But as technology came along it became apparent that typewriters were not equipped withso attempts were made to use the lower case "l"(el).
Then it became further confusing to write "1l" (lower case "el")
as the "1" and "l" (el)looked too similar as did the capital "I" (eye). So the capitalLwas chosen as thesymbolfor
the derived base unitliter.
That is the only exception in this so keep going!
