So if a prescription calls for 2 teaspoons of a liquid, how does that convert to milligrams? For instance, one website says take 2 teaspoons of aloe vera, then another says 100-200 milligrams. So how many milligrams in 2 teaspoons would that be? :-) thanks, guy! (and gals...)

Did you know Google will convert almost any number to any other related number? Monetary exchange rates, weight to density for various materials, acres to yards to feet to inches, metric conversions... give it a whirl.

You are, by the way, trying to convert a volume measurement to a weight, which you can't do without knowing the content weight of the goop. It's easy with water, sand and cement, not so easy with substances whose manufacture and processing may vary considerably.

But goog up "2 teaspoons water to milligrams" and you'll have a start. Keep in mind, as above, that 'milligrams' in dosage calculation assume a standard formula, etc. 50 micrograms of medicine per ml of solution. Conversions are thus not universal, although most pharmacy preparations try to stay near a standard ratio.

I am pretty sure more precise indication you will find directly on the bottle.
Don't worry, though, as an oral supplement, aloe has no set dose.

I kind of skipped over it being a non-USP, folk-formulated substance.

I do believe a lot of problems with supplements and alternative medicines that might otherwise be benign to helpful is that dosing (including measuring desired doses) is often... haphazard to whimsical to 'if a little's good, lots is better.'

All three can be a little tricky unless you were just looking for rough measurements. Water or liquids will expand and contract with heat/cold. I had an Uncle in the oil delivery business, he would always try fill the truck the day before and let it sit somewhere warm... tricky. Cement is pretty consistent product but would take up less space if for example it were vibrated. The sand can have the widest ranges. There may be water weight, sand from different sources can have different densities and the sizing of the sand can have significant impact.

A finer sand will take up more space than larger sized sand. This may sound counter-intuitive but the smaller a bulk product like that is the more surface area it has, this creates more gaps which may be smaller but the volume of them as whole is much larger.

If it were coal one size is rice about the size of a pencil eraser, over a 5 ton load you can see the volume difference by eye compared to something like chestnut(another size) which is typically a little bigger than a golf ball. There might be a difference of about 10 to 15 cubic feet.

Here's one. Let's say you have a gallon of liquid A in one container and a gallon of liquid B in another container. You take a cup of A and mix it into the B container and stir it up. Then you take cup of that mix in B and pour it into A.
Is there more A in the B container or more B in the A container?

OK, I give up and just scratch my head. No wonder I stopped at trigonometry in high school (I liked trig, but didn't go on to physics). :-)

Not if the liquids are alcohol and water. 1 liter of water and 1 liter of ethanol will make about 1.92 liters of solution. (I figure if someone is going to go all civil engineering on my offhand comment about cement, I can go all chem major on this... )

Isn't that about volume, not weight?
A gallon of syrup weighs 11 pounds while gallon of alcohol weighs only about 6.5 pounds...

OP is talking about weight: "how many milligrams in 2 teaspoons would that be?"
