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).
A milliliter (also written milliliter; SI symbol ml) is a non-SI metric system unit of volume which is commonly used as liquid unit. It is equal to 1/1000 liter, or one cubic centimeter, therefore, 1ml =1/1000 L =1 CM3.
