No, it is not equal.
As long as it is not whipped cream, one milligram is more.
density value is required, If it is 1 gram/cm3, then it is the same (ie 1 milligram = 1 milliliter)
No. A "cc" (cubic centimeter) is an old term for a milliliter (ml) which is a unit of volume. A milligram (mg) is a unit of mass.
One milliliter of pure water.
Divide by 1000.
No, a gram has a volume of 1ml.
Milliliter is a measure of volume. Milligram is a measure of mass. 25 mL doesn't have a weight on its own - it depends on what you have 25 mL of.
Good luck. There is no such operation. "Milliliter" is a volume ... a little piece of space. "Milligram" is a tiny amount of mass. Before you can tell how much mass there is inside a piece of space, you have to know what substance you're talking about: -- If the substance is air, it's a small amount. -- If the substance is water, there's roughly 1 milligram of mass in each milliliter of space. -- If the substance is lead or gold, there's a lot more mass in every milliliter. -- And if the milliliter is empty, then there are no milligrams of mass in it at all.
They measure different things: 1 milliliter is a measure of volume, whereas 1 milligram is a measure of weight.
A milligram is a measure of mass just like a kilogram, while a gallon is a measure of volume. You cannot directly equate mass to volume. Under some idealized conditions a milligram of water is one milliliter. A milliliter is a unit of volume. There are 204,412 milliliters in 54 U.S. gallons
1000 ppm is equivalent to 1 milligram per milliliter.
