Sometimes chemicals are reported as a ratio of weights or moles. These can be converted to the opposite relation if the molecular weights are known.
Example: Converting a urinary oxalate to creatinine ratio expressed in mg/mg to mol/mol
NOTE: This applies if the units for both chemicals are equal. If the units are not equal (mg/g, mmol/mol, etc.) then a more complex conversion is needed.
If the weight ratio is known:
(molar unit of chemical 1) / (molar unit of chemical 2) =
= (weight unit of chemical 1) / (weight unit of chemical 2) * (molecular weight of chemical 2) / (molecular weight of chemical 1)
If the molar ratio is known:
(weight unit of chemical 1) / (weight unit of chemical 2) =
= (molar unit of chemical 1) / (molar unit of chemical 2) * (molecular weight of chemical 1) / (molecular weight of chemical 2)
