386 grams, the extra 0.2 grams is not only irrelevant it's non existent because the process of converting from one measurement standard to another never increases the precision of the measurement.
Using 3 digits of precision also avoids being temped to use the rather niche ,2 convention when claiming to embrace a region as large as the rest of the world.
Interesting notion, but how do you know it's 13.6 and not 13.600?
By convention if it was 13.600 they would present it as 13.600 not 13.6. If I remember correctly Everest was first surveyed as 29000 feet tall and they changed it arbitrarily to 29002 to avoid the apparent imprecision!
