ml to mg calculator


Free online ml to mg Calculator allows you to easily convert milliliters (ml) to milligrams (mg) for various substances such as water, milk and cooking oil.

The formula of ml to mg

To convert ml to mg, you can use the following formula

Mg = ml * D

  • Ml = milliliters
  • Mg = milligrams
  • D = Density of substance (mg/ml)

Density value of some substance

  • water:- 1000 mg/ml
  • Milk:- 1030 mg/ml
  • Cooking oil:-  916 mg/ml
  • Other:- 1000 mg/ml(same as water density)

How to calculate ml to mg?

  • First, Determine the volume in milliliters
  • Next, Determine the density of the substance (unit – mg/ml)
  • Finally, Volume (ml) is multiplied by density (mg/ml) then weight in milligrams

Solved example

For example:- If you have 100 ml of a liquid with a density of 1.8 mg/ml, then calculate milligrams

Given Values-

  • Volume of liquid = 100 ml
  • density of liquid = 1.8 mg/ml

Milligrams = milliliters * density

mg = 100 ml / 1.8 mg/ml

Milligrams = 180 mg

So, 100 ml of a liquid with a density of 1.8 mg/ml is equal to 180 mg.
