You guys forget "chains", "stones" and "furlongs" for starters.
In school, we had to calculate the speed of light in furlongs per fortnight!
Oh, and there is a French measurement that translates to "horse gas hours" which is probably like horsepower in Englis.
One hour of horse gas is probably one too many.
1 MILLILITER equals .0022 of an imperial gallon

The International System of Units, abbreviated and commonly known as the SI, is officially known as Le Système International d'Unités and is overseen by the Bureau International des Poinds et Mesures located near Paris, France. Their website is
and their mission, as quoted from that website, is to "provide the basis for a single, coherent
system of measurements throughout the world, traceable to the International System of Units..."
So, the SI can handle British Barns and any other thing you want to throw at it. :-)
And all these things made perfectly good sense at the time they were the standard.
Let's take a moment to thank our French cousins for freeing us from the Imperial baloney we once relied on.

I was asking about millimeters! My idea of humor...

i see, that's actually funny. my mistake, but 1 milliliter is .00022 of an imperial gallon, not .0022.

if you have a box camera ... you could expose your film, and process it in dilute dektol
for a little longer than you might normally ( if you ever normally processed film in it it used to be suggested 7 min / 1: 7 )
to build up density and contrast ...
cut your film down and make contact prints ...
you might consider paper negatives make with a camera of some sort
to make contact prints on your paper.
i love making photograms on azo i have
good luck ( and have fun )

I don't remember exactly, but it seems to me Kodak began the move from packages of 12 and 144, to 10, 25, and 100 around 1950-1955. Agfa and others followed along soon after.
I have always thought it ridiculous to sell sheet film in boxes of 25 which means one can load 12 holders and have a sheet left over in the box. Paper was boxed in the same quantities as film.

And, try the old English units for money used up until 1971, Pounds, Shillings and Pence.
If you really want to get confused on old measurement systems get stuck in looking at old English systems for acres, townships, etc
12 penny's in a Shilling, 20 Shillings in a Pound.
