To make lemon balm tea, add a handful of lemon balm leaves to 1 cup of water and steep for at least five minutes. For a soothing lemon balm bath, put some fresh (or dried) crushed lemon balm leaves into a muslin bag, then let the warm water run through it as you fill the tub.
If you have pure water then a ml is equal to a mg. Water is the only substance where this is true, because water was used as a common substance when devising the metric system, based on the earth. . Absoultely not! ml is milliliter, a measure of volume and mg is milligram a measure of weight. No. ml is milliliters 1ml=0.001l (1/1000 liters). This measures volume of a liquid. mg is milligrams 1mg=0.001g (1/1000 gram).
No set answer to that.   Gram is an unit of weight while ml is an unit of volume - the  result will depend on the density of the substance. One ml of lead  will be a lotâ¦ heavier than than one ml of sugar.   Only if you have pure water in mind: 1 milliliter of pure  water weighs 1 gram.    1 g = 1000 mg.
