Measuring Mg with a Tablespoon?

Is that possible?? I know there are 15mls in 1 tablespoon, but how would i measure the mgs without a scale?

It only works if the substance you are measuring is a liquid, but a tablespoon of a liquid = 15 grams.  If it's something light and fluffy, like puffed rice, then this wouldn't apply.

 Moreover, it only works with water and things that weight exactly the same as water.  This won't work for oil or alcohol, for example, as they are lighter than 1g/mL. 

If you want to be accurate, you really need a scale, unfortunately.

Just to add for measuring mg you need special scales. Most food scales only do in grams and have error of +- 2 or 5 grams.

I would venture to guess that most liquids are roughly the same density as water and 15 ml = 15 grams is probably close enough for most uses.  You'll be off by a gram or two here or there but not much more than that.  The same goes for larger volumes.  A quarter cup is approximately 60 ml or 60 grams, 1 cup is approximately 250 ml or 250 grams.  Also, 16 tbsp to a cup...etc.   It won't work for powders obviously or other solids, but for liquids I think it's close enough.

Other then mantaining a database???

water, milk and eggs (in liquid form) -- 1 cup (volume) equals 8 ounces (weight)

Anything else, the weight changes.  It also depends on how you put items in a measuring cup/spoon. 

Thankyou very much, appreciate the help!
