Depends on the substance. A given volume of one substance can weigh more or less than the same volume of another substance.
In terms of water, 1 mg (milligram) = 1 ml (millilitre) so 1000
No, 300 mg per cc does not equal 25 mg per kg. To convert 300 mg per cc to mg per kg, you need to know the weight of the individual in kg. If you're looking for a general conversion, you would typically need to know the volume of the substance in cc and the weight of the individual in kg to determine how many mg per kg 300 mg per cc would be.
A millilitre is a unit of capacity. A milligram is a unit of mass. The two units are therefore incompatible.
620 (mg per liter) = 62 mg per deciliter.
A millilitre is a unit of capacity. A milligram is a unit of mass. The two units are therefore incompatible.
There is no equivalence. A milligram is a measure of mass. A millilitre is a measure of volume. The two measure different things and, according to basic principles of dimensional analysis, conversion from one to the other is not valid. If you are not convinced, consider a millilitre of air. How many milligrams? Next consider a millilitre if mercury. How many milligrams?
cubic centimetre = cm3 = millilitre how many ml in one mg assuming density = 1g/ml (you need to know density), then 1mg = 1ul 1ul = 0.001ml
This question cannot be answered sensibly. A millilitre is a measure of volume, with dimensions [L3]. A milligram is a measure of mass, with dimensions [M]. The two measure different things and basic dimensional analysis teaches that you cannot convert between measures with different dimensions such as these without additional information. As a simple mental exercise consider a millilitre of air and a millilitre of water. They will have very different masses.
