Weight of RODI water?

[mike550]

Hello! I’d like to mark a few containers for 1G of volume, but I’m thinking that weighing 1G of RODI water will be more accurate than trying to measure and pour in cups etc. That said, can I assume that 1ml of RODI weighs 1 gram?

So then 3875mls of water / 3.875kg / 8.543lb

Correct

A container with a mark at the one gallon level works very well.

Almost perfect, just a little dyslexic. 3785mls = 1 gallon. So 3785 grams = 8.34411 Lbs.

At what elevation?

Sea Level! (or the level of my own insanity, your choice.)

The mass of water with a volume of 1 gallon will vary by temperature.

One gallon is 3785 mL.

At 70 deg F, that 3785 mL of water weighs 3776 g.

At 80 deg F it weighs 3772 g.

Ugh! Thanks for the check! Yes. I’ll go 3.785kg

Ah, but @Randy Holmes-Farley is absolutely correct. (you're killing me Randy, you're killing me! I luv it!) So, max difference, 3785G - 3772G = 13g = 0.0286598Lbs. or 0.003434237 Gallons. I think I'll go with @exnisstech idea. But as @The_Paradox mentioned, what elevation?

Did you factor in the moon’s gravitational pull? Lol
