The conversion
- 1 mg/L = 2.322 µmol/LFrom mg/L to µmol/L: multiply by 2.322. Back again: divide by 2.322.
- 1 mg/L = 0.1 mg/dLFrom mg/L to mg/dL: divide by 10. Back again: multiply by 10.
- 1 mg/L = 100 µg/dLFrom mg/L to µg/dL: multiply by 100. Back again: divide by 100.
Mass and molar units are linked by the molecular weight: 430.7 g/mol (alpha-tocopherol, C29H50O2 (PubChem CID 14985)).
Common values
From zero to about twice the usual upper limit, plus the usual limits themselves.
