How much is 5mg in ml?
5 mg is 5/1000 g and that volume of water would be very close to 5/1000 ml or 0.005 ml.
How do you calculate mg per ml?
Divide the mass in milligrams by volume in milliliters to find concentration in mg/mL. For example, if you have 8,000 milligrams of sugar dissolved in 200 milliliters of water, work out 8,000 ÷ 200 = 40. The concentration of the solution is 40 mg/mL.
