OGRA archive · conversion methodology
The assumptions used for the green USD/metric-ton values in the archive, including both gasoline grades.
Density-based products use the supplied barrel definition and an editable product density.
Kerosene at 0.800 kg/L = 7.86243 bbl/MT. Gasoil at 0.845 kg/L = 7.44372 bbl/MT.
The archive derives High Sulphur Gasoil from OGRA Gasoil 0.05%:
Its USD/MT value then uses the shared gasoil density.
The archive converts every published Gasoline 95 USD/bbl value using the Platts factor:
The generator applies this factor to the full-precision published USD/bbl value on every archive update.
Gasoline 92 uses the same fixed Platts factor in the historical table:
The same rule is used in the desktop table, mobile cards and latest daily card.
A factor of 8.5 bbl/MT is mathematically equivalent to approximately 0.739993 kg/L with a 158.984-litre barrel. This is a calculation equivalent—not a claim that every gasoline cargo has that physical density. The conversion lab keeps separate Gasoline 95 and Gasoline 92 density controls so either grade can be tested independently.
Blue-grey cells are values published by OGRA.
Green cells are conversions or derived values calculated by this archive.
