Unit converter
Convert between milliliters (mL), milligrams (mg), microliters (µL) and micrograms (mcg). Enter a value in any unit to see its equivalent in the other three.
Milliliters to milligrams
5,000mg
5 mL equals 5,000 mg.
Mass and volume are related here at 1 mL = 1000 mg, the density of water. For a peptide dose in milliliters, use the vial's own concentration in the main calculator.
How the conversion works
Mass units convert exactly: 1 mg is 1000 mcg. Volume units convert exactly: 1 mL is 1000 µL. Between mass and volume the converter uses 1 mL = 1000 mg, the density of water, so 1 µL = 1 mg.
That relates a volume to the mass of the liquid itself, not to the peptide dissolved in it. For a dose in milliliters, use the main calculator with the concentration of your vial. The converter is intended for precise scientific and laboratory measurements.
