Some Pen Weights

I like small, lightweight fountain pens. The pens listed have been weighed on a digital postal scale. The scale rounds up or down to the nearest gram. (Your pen’s weight may vary slightly.) While I write with my pens unposted, the posted weight is listed for those of you who may be interested in that information. These pens do not represent my collection. (It is here.) They have all been weighed on my scale.

If you need to convert grams to ounces, try this converter here.

Some of my thoughts about ink capacity.

PenPractice.com has a nice list of vintage pen ink capacities.

c/c = cartridge converter; cf = crescent filler; ED = eyedropper; lf = lever filler; PIF = piston. For c/c pens weight includes converter not cartridge. Average international converter weight between 2-3 grams. Generally, any ED pens on the list below are converted from c/c. Weights for pens listed as “c/c or ED” indicates the weight is the same using either method (the ED will hold more ink, however).
