Conversion of oxytocin levels between units

Conversion of different size units:

1 Unit (IU) = 1000 milliunits (mU) = 1000,000 microunits (μU)

1 g (g) = 1000 mg (mg) = 1000,000 micrograms (μg) = 1000,000,000 nanograms (ng) = 1000,000,000,000 picograms (pg)

1 Mol/L = 1 Molar (M) = 1000 milliMolar (mM) = 1000,000 microMolar (μM) = 1000,000,000 nanoMolar (nM) = 1000,000,000,000 picoMolar (pM)

Conversion of units (U) to weight units:

1 IU = 1.67 μg, 1 μg = 0.60 U

1 mU = 1.67 ng, 1 ng = 0.60 mU

1 μU = 1.67 pg, 1 pg = 0.60 μU

Conversion of weight/volume of oxytocin to Molarity (molecular weight of oxytocin equal to 1007 g/mol):

1 g/mL = 1 mol/L = 1 M

1 mg/mL = 1 mmol/L = 1 mM

1 μg /mL = 1 μmol/L = 1 μM

1 ng/mL = 1 nmol/L = 1 nM

1 pg/mL = 1 pmol/L = 1pM
