I just wanted to ask everyone how they measured water volume? I didn't have a graduated cylinder to measure water volume with but I did have a scale. I remembered that the weight of water is typically around 1 gram per ml so it made it very easy to measure fairly precise amounts. It's really useful when trying to compare exact ratios in different sized pots or simply when measuring the volume of a pot. I know many people prefer a more natural and intuitive approach and certainly I would agree when I am drinking normally but once in a while it's fun to let out my tea-scientist side a little too haha.
I know there are a few people here who are more scientifically inclined than me so please correct me if this method is way off but so far it appears to be very precise. Not only is it precise bit also nice because I can simply put the pot on the scale, zero it out, and then pour the exact amount of water I want on a given infusion.

Anyway, I might have to find some cups and test it for myself further.

I remember reading how innaccurate graduated measuring cups were.
I guess I will have to do some weighing ...

Anyway, I too have never purchased something that matched exactly the advertised volume. I have two kyusu from Hojo that differ by a fair amount: 1 was advertised as 150 and comes in at closer to 160 while one was advertised as 200ml and comes in closer to 180. Not a huge deal individually but then instead of 50mL difference between the two they are very comparable in size...not really a huge deal for me I suppose. Anyway it'
's still nice to be able to measure volume so quickly and easily.
