Units: Companies may report the volume in thousands of cubic metres, or using a unit other than cubic meters. If this is the case, convert units to cubic meters (see website below), or add the number of zeros indicated, and fill in the total number in the answer field - e.g. If the company says '0.5 million cubic metrics' the answer should be entered on WikiRate as '500000'.
