You don't. 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 elementary 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 of water. They will have very different masses.
You can not convert mg (weight) to volume (ml).
To calculate the concentration of the sucrose solution, you would divide the amount of sucrose (125 mg) by the total volume of the solution (500 ml) and then convert the units as needed: Concentration of sucrose solution = 125 mg / 500 ml = 0.25 mg/ml = 0.25 g/L
Only if the density or concentration is 1 mg/ml
To convert milligrams (mg) of amoxicillin to milliliters (ml), you need to know the concentration of the amoxicillin solution. For example, if you have a concentration of 125 mg/ml, then 250 mg would be 2 ml. Without the specific concentration, you cannot directly convert the mass to volume. Always refer to the medication's labeling or consult a healthcare professional for accurate dosing.
This is not a valid conversion. Milliliters (mL or ml) and liters (L) are measures of volume. Grams (g), kilograms (kg) and milligrams (mg) are measures of weight or mass.
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
