Calculation of grams to ml

[bellac11]

A really stupid question but if I have a can of something which says 400g but which is pure liquid, is this the same as 400ml. Ive eaten it now and didnt measure it and need to know.

thanks

I’m afraid it depends what it is. You need the average density of whatever it was. If it’s water then yes, it’s 1g/cm3 which roughly matches 1g/ml.

400mL of water weighs 400g.
But if wasn’t water then the calculation could be different.
If it was mostly water (eg. Apple juice, squash etc) then 1gm = 1mL is probably accurate enough. But if was a can of soup, for instance, it might be significantly different. Ice cream is significantly lighter than water too for example.

For water 1g is 1ml is 1cm3 so as a rule of thumb liquids should be roughly the same…

Yes for water 1ml weighs 1g and most other liquids used in cooking will be close enough

But glucose (I’ve just Googled ‘density glucose g ml’) is 1.8g/ml.

If the can is pure liquid it will be equivalent. The relative density of the fluid will be negligible at that level, unless it’s a can of honey!

Water is 1ml = 1g

Oil and cream are less dense so 1ml < 1g but given the accuracy of kitchen scales and the amounts in recipes it doesn't make a huge difference

It was beef consume, Baxters if it makes a difference!!

Have you still got the can? Assuming it was full to the brim, just measure the volume of the can.

That would have been a very good idea! Dont know why I didnt think of that. I counted 400ml for it in the end

This reminds me of a time when I had a can of liquid and needed to figure out how much was left after I used some. I found out that 400 grams of pure liquid usually equals 400 milliliters because the density of most liquids like water is about 1 gram per milliliter.

It was helpful to know that in this case, the weight and volume are essentially the same. For a bit of extra info, I also checked out troy ounces to grams (about 31.1 grams per troy ounce), just to get a better grasp on different measurements. It’s these little details that make things easier down the line!
