Correctomundo Z13. The Dram Equivalent was meant to be the measure of black powder that was equal to what was in the shell. This number was an invalid number though due to several different things such as how fine the black powder was, the potency of the black powder etc. The fps is just a reference as to how fast the shot SHOULD go if it were three drams of black powder. Dram is not a measure of velocity but a measure of weight. You can actually google how many drams of black powder equals how many grains of smokeless powder. As one of these grey beards, I have misplaced the bookmark I had on this or I would have posted it here.

I’m resurrecting this thread because, while looking up some information, I came across this statement.
From the Alliant Powder Reloaders’ Guide, 2004 Edition, page 56:
Which is exactly what I argued.

Simply stated, the dram equivalent is an indicator of the velocity of a particular shot load.
Which is exactly what I argued.

.45 COLT,
IMHO, I beg to differ, that's not exactly what you argued. Your initial statement (reply #6) was: "… DE is a measure of velocity, dependant on charge weight…" The Alliant Guide definition is qualified by: Simply stated and an indicator of. Yours is unqualified. Blue litmus paper turns red under acidic conditions. It's an acid indicator; but, it's not an acid. DE may be an indicator of velocity (as stated by Alliant), but it is not a measure of velocity (as you originally purported). Hopefully you appreciate the difference.
You may wish to ponder: A measurement is a constant; therefore, it can't be a variable (dependent or independent).

Dram Equivalent tells you the velocity of the shot charge as it leaves the muzzle. Period. Now if you want to call it an indicator or a measurement, I don't care. A Speedometer indicates how fast my pickup is going. I'll maybe say it measures the speed. My contention that energy isn't part of the equation stands.
