You are comparing 2 different things: weight and volume. So this question cannot be answered, unless you tell me what substance you are working with =] First of all, mg is a measure of weight and ml is a measurement of volume, to determine how many ml 400mg is we need to know what density or Specific Gravity (SG) the substance is. Water has a SG of 1 and a density of 1kg per liter.
there are 1000mg in 1 gram and a 1000 grams in a kilogram (about 2.2 pounds) so 400mg=0.0004 kilograms.
The density of Gold is about 19.3kg per liter ( or 19.3 grams per ml).
The formula for density is D=m/v (Densityequals mass over volume) Mass divided by volume.

ProfessorActually, mg is a unit of mass, and mL is a unit of volume, therefore they're not equal at all. It all depends on what substance weighs 400mg. Get the density of that substance, and use that to convert to mL using D=M/V (Density=Mass/Volume). Or, since you're solving for volume, it would be M/D=V (Mass/Density=Volume)
Grams (g) or Milligrams (mg) are a dry mass measurement.
Litres (l) or Millilitres (ml) are a fluid measurement of volume, and subsequently, they don't convert with one another.
There is an exception to this rule. 1g of water has a volume of 1cm3 which equates to 1ml at room temperature.

What does 400 mg equal to in tablespoons?
Ah, a delightful question! 400 mg is approximately equal to 0.08 tablespoons. It's important to be precise when measuring out doses, just like when adding the perfect touch of color to a painting. Remember, a little goes a long way!
How many mls of 50 mg ml of Rocephin equals 1.5 gms?
To calculate this, we can use the formula: Amount (g) = Concentration (mg/mL) x Volume (mL). Given that 1.5 g is equivalent to 1500 mg, and assuming that the concentration of Rocephin is 50 mg/mL, we can rearrange the formula to solve for volume: Volume (mL) = Amount (mg) / Concentration (mg/mL) = 1500 mg / 50 mg/mL = 30 mL. Therefore, 30 mL of a 50 mg/mL Rocephin solution is equivalent to 1.5 g.
Formalin 400 ml in to grams?
Formalin is 37-40% formaldehyde in water. Therefore, 400 ml of formalin would weigh approximately 335-360 grams.
How many mg per ml are needed to administer 2 g in 150 ml per minutes?
To administer 2 g in 150 ml over a specific time period, you need to find the concentration in mg per ml. First, convert 2 g to mg (2000 mg). Then, divide the total amount (2000 mg) by the total volume (150 ml) to find the concentration: 2000 mg / 150 ml = 13.33 mg/ml. This is the concentration you need to administer per minute.
How many ml in 80 mg of Megace?
The concentration of Megace is generally 40 mg/mL. To calculate the volume needed for 80 mg, you would divide 80 mg by 40 mg/mL, resulting in 2 mL.
