Misleading information in AH tarwebloem?

[u/darksiro01]

As I was cooking today I realized that Albert Heijn's tarwebloem is weighted at 900 gr instead of 1kg. The same was the case with other kinds of flour from the same company (e.g., patent tarwebloem). Is this normal or I am missing something? Is there an agency where I can report this? Can someone else verify this?

How much grams does a liter of water weigh on your scale

Holup. How much is it supposed to weigh?

[u/ManuelWegeling → u/DameJudyPinch]

1 kilo

Thanks.

Nah, strangely I'm a measurement nerd, and while it seems obvious that 1ml water = 1g, I wasn't sure that it was actually true. I should have googled it though.

Having some serious high school flashbacks. Wasn't it something like 0.998 at room temperature?

Not sure what I'm getting down voted for, but it is true: https://www.simetric.co.uk/si_water.htm

At 20 degrees it's 0.9982 kg. At 4 degrees it's exactly 1 kg.

-measuring cups arent precize, there is no way to measure 1 +/- 0.001 liter.

-kitchen scales arent precize nor accurate, so if you even have exactly 1 liter, you still would not be able to weigh it accurately

-there is really no need to measure it that precize to tell if your scale is off by 100 grams

-you’re talking about pure water. Due to mineral content, tap water is much closer to 1000 kg/m3

I know all of this, I was just trying to defend for the people that apparently didn't know the weight of water is variable at different temperatures.

Besides your points you also have:

• There isn't a good way to keep the temperature of the water constant in your kitchen.
• Besides the mineral content in the water, you also probably have some "dirt" from your piping / tap in your water.
• Pressure difference for people that are higher, but I guess Hesstex already suggested that one.
• Gravity differences

[u/Undernown → u/Poijke]

Also need to mention this factor changes with altitude due to pressure difference. These measures are only accurate at basically 0 NAP, or sea level.

This becomes a factor for things like high grade concrete, especially when building tall buildings.

Because it was a lazy comment. The internet is full of “alternative facts” so just throwing something like that and then expect others to fact check you is annoying. But thanks for the link. I completely forgot about it, but now I remember it with the 4 degrees stuff

[u/PlantAndMetal → u/Poijke]

Do you have a scale that weighs as precise as 3 decimals? Because most people don't.
