[USMA:36026] More non-SI usage

[Bill Hooper]

The Philippine coal production consistently maintained the 1.1 million metric tons (MMMT) level from 1996 to 1999 prior to its rise to 1.4 MMMT in 2000. I got this reference recently when looking for energy data. I'm not sure if it is from a Phillipine source or a different source quoting Phillipine data. I'm really astonished at the abbreviation they've used for the mass unit. How they got THREE M's for "Million Metric Tons" (which has only TWO M's) I'll never understand. Furthermore, since a million tons is 1000 tons and  a ton (or tonne) is 1000 kg and  a kilogram is 1000 g,  that makes a million tonnes equal to 1000x1000x1000 g  which is 10^9 g or 1 Gg (one gigagram).  Surely their two quoted pieces of data  (1.1 MMMT and 1.4 MMMT) would be more easily stated as:   1.1 Gg and 1.4 Gg Regards, Bill Hooper Fernandina Beach, Florida, USA ==========================    Make It Simple; Make It Metric! ==========================
