For measurement  I use a digital scale with a resolution of 0.01g. I weigh the pen empty, then fill in water and weigh it again. The difference in g is the same in cc with reasonable accuracy.

Also, more ink is not always better.  Whenever go you above 2 cc, then you need to start worrying about ink surges which may overwhelm the feed, then your pen may burp up drops of ink onto the page.  I never saw that happen with my New Postal Jr, but I have seen it a couple of times with the Edison Glenmont.

 

It regularly happens with eyedroppers (and other pens with the ink floating around in the pen shaft) when the ink reservoir is near empty. It happens more easily with eyedroppers with "simple" feeds (like the Indian Wallity feed which goes into many stock Indian pens). Pens with more moderne feeds with lots of fins in the section like Jowo feeds are less prone to this blurping. I use to fill my eyedroppers when the ink level goes below ½ full. Luckily, eyedropper holds a lot of ink, so that's no problem. My Indian Gama Hawk and other Gama "Jumbo" sized pens takes around 4ml of ink (pretty accurately measured because I fill it with an injection syringe).

I also use a digital scale.  Excellent scales can be found for less than $10. 

 

I weigh ink, which is very close to the weight of water.  So when I fill a pen, I weigh how much ink it drank.

 

With converters, you can see the level of the ink, which is often less than full on the first pass.  But with pistons, weight is all you have.  They respond like converters and often drink more ink on the second or third pass.

 

I also use weight to determine how much ink remains in my piston pens, before taking a pen out for a meeting or work.  I keep a record of the empty weight of each pen in order to determine how much ink is left when I weigh the pen.

I am fascinated with this topic. Is all of this concern with capacity so that one doesn't run out unexpectedly? I just carry 2 pens, but they are usually filled with something cheap and boring.

 

Here are some vintage fat boys.

 

Carey slip cap eyedropper               9.2 ml

Waterman 48s                                  5.6

Moore #12 Jumbo Safety                 4.8

 

Had to dust off an old graduated cylinder for this one. Assume a fairly wide margin of error.

Not a measurment but as they say, one pic is sometimes worth two or three words: a vintage tortoise 400nn vs a year 2000 demo m250. Note where the pistona are when fully retracted...

Edit to add: quotation from Francis, aka Fountainbel, from the French forum Stylo-plume.org

"
Modern 200/400 : piston bore 8.2mm, piston stroke 24.5mm, potential ink volume:1.29 ml
Modern 600 : piston bore 8.2mm, piston stroke 26 mm, potential ink volume:. 1.37 ml
Modern 800 : piston bore 8.2mm, piston stroke 26 mm , potential ink volume: 1.37 ml
Modern1000: piston bore 8.2mm, piston stroke 28 mm , potential ink volume: 1.47 ml
Vintage 400 : piston bore 9.0 mm, piston stroke 31 mm , potential ink volume: 1.97 "

I suspect a lot of people feel like "more is better" and are proud of getting a pen with as much ink capacity as possible.  As I studied this subject, however, I've come to believe that more is not better, and that the ideal ink capacity is actually about 1 ml.  If the amount is much less, then you'll just have to refill needlessly.  If it's much more, then the ink flow becomes more difficult for the feed and ink collector to regulate, less consistent and less efficient.  When you get up to very large capacities (say above 2 ml) "burping" ink onto the page is a real danger.

 

As I noted way back at the beginning of this thread, it's interesting how many of the most famous and successful designs clustered around the 1.0-1.1 ml mark.  I don't think it's an accident.

I guess it depends of what you use your pen for. When writing outside my home, ink capacity is a factor. It's not unusual that I will empty two "regular" piston fillers (say, Lamy 2K or Pelikan m2xx), esp. when writing with B or BB nibs.

My beloved Densho with a B nib will drive me through a good day of writing and I do have a backup just in case, ED filler too.

Of course if you are taking a few notes or using the pen for other writing tasks (planning, journaling...), capacity may not be a factor.

Edit to add: also, it's a commonplace that piston fillers or vac fillers per se "hold a ton of ink" - we can see here it's not the case.

This is the 400nn..........."""Vintage 400 : piston bore 9.0 mm, piston stroke 31 mm , potential ink volume: 1.97 """"

Well, I'm pretty sure....I always forget to weigh my 400nn....and it is a smidgen longer at medium large vs a standard 400.


Everyone says poor Mozart dead at only 36. None say poor Mendelson, dead at only 38. His family only allowed him to start at 20, but before, musicians use to come to the Mendelson garden to steal the music of Mendelson and his sister. A good artist also, can still buy prints of his famous Scottish drawings in Scotland.

I thought I would add three of the new Chinese piston-filler pens

 

Wing Sung 3008 - 1.2 ml

Wing Sung 698 - 1.6 ml (someone else's measurement, not mine)

Caliarts Ego - 2 ml.
