I know it’s the most expensive liquid by fluid oz, but is it more expensive than gold by weight too?
Gold is 19.32 Kilograms per litre. 1kg is 35.274 ounces. One ounce of gold is currently 3429 USD. So one litre of gold is 3429 × 35.274 × 19.32 = 2325956 USD.
Printer ink is 23.05 USD per litre per bulk refill, but standard desktop cartridges typically hold just between 3 to 10 milliliters of ink, costing USD 20 to 50, so USD 200 - 16666.
So no. But ppl are definately ripped of depending on what ink packs they buy. Easy to check with gold.

Thanks for doing the math, also I haven’t bought printer ink in almost 20 years, after the last time it asked for yellow to print a b/w page. I still have my old wide format epson in my damn attic though, mostly since I was planning on using the motors and linear rails for a camera mount someday.
