Weight of 1 teaspoon of Salt (an observation)

[silver]

The textbook answer seems to cluster at around 5.65 - 5.7 grams per TSP.

But using 2 separate measuring teaspoons in conjunction with my container of table salt (Aldi brand), and carefully leveling them,  I'm highly consistently seeing on average 6.6 grams per TSP.

However, I also have Flour Salt on hand for use in my fried chicken coating mix recipe efforts, and using the same two measuring teaspoons it consistently comes in at 5.4 grams per level TSP.

I'm merely tossing this out so everyone will be made aware of the high variability in volume measure vs. weight measure.

Wikipedia lists the bulk (or unground) density of NaCl at 2.17 grams/CC. If the standard Metric measuring teaspoon has a volume of 5 CC, then:

5 x 2.17 = 10.85 grams per teaspoon.

Obviously the finer salt is ground, the less it weighs per unit of volume.

This pattern likely rings true for other substances as well...

silver,

I reckon if you were to line up three cooks and ask them to carefully weigh out 3 separate teaspoons of Salt each, that the chances of two teaspoons weighing the same would by extremely slight. It’s why I prefer to use scales/weights instead, but even those may vary slightly depending on height above sea level, particularly if you live at the top of a mountain, but the cooks average weight for table salt in many cook books is 6g.

So a 3lb bag of Salt used with 25lbs of flour, if the flour is scaled down to 400g for Home use, that would be in the region of 48g, which equates to 8 teaspoons of Salt, or simply put another way it is approx. … 2 teaspoons of Salt for each 100g Flour used. I think that’s a reasonable average to use but as you infer, the same weight of various Salts do alter by volume. (and vice versa)

One must also consider that the volume of a certified "measuring teaspoon" in the USA is 4.929 CC, whereas the Metric "measuring teaspoon" has a volume of 5.00 CC.

And a certified USA measuring "Cup" has a volume of only ~236.59 CC, whereas a Metric measuring Cup has a volume of 250 CC.

250 CC/48 = 5.2 CC (which does not equate to a Metric 5 CC teaspoon)

236.59 CC/48 = 4.929 CC (which does equate to a USA teaspoon)

There are actually 50 Metric teaspoons in 1 Metric Cup.
