I bought some Brie cheese at Costco yesterday.  It was from France, but with
the Kirkland (store) brand.  The indication was 17.6 oz/499 g.  No doubt it
started out as 500 g, then got converted to 17.6 oz, then someone
back-converted it to grams again.

Subject: [USMA:51964] The foreign press does poorly on Customary/metric
conversion too.

 

Anytime you have one system and one collection of arbitrary units competing
with each other there is going to be a need to convert from one to the
other.  Conversion mistakes will always occur, especially if the converted
number is rounded.

 

And if you have back and forth conversions, with a lot of rounding you can
end up with more errors then you shake a stick at.

 

One would think the errors would be minimal if the news agencies use on-line
converters.  If they convert manually, any thing can happen.

 

The only way to stop the errors is for the media to come to an agreement to
use one system (SI) universally.

Noticed two articles that got it pretty wrong:
 
First, Reuters says the amount of a fuel spill is "unknown" but then quotes
a 
third-hand Coast Guard estimate, but how about those "super-liters."  I
doubt 
NBC said anything about any liters.  The good news is several commenters on
the 
article noticed.
http://news.yahoo.com/fuel-spills-waterway-between-jersey-staten-island-0129
13605--nba.html
"NBC, citing the U.S. Coast Guard, said 300,000 gallons (115,000 liters) of 
diesel fuel had been released."
 
This article is attributed by copyright to Deutsche Presse-Agentur.  In the 
Kia/Hyundai fuel label scandal, it correctly reports the claim that the Kia 
fleet average, corrected, falls from 27 to 26 mpg.  It incorrectly converts
to 
liters per 100 kilometers, making a 3% change become a 10% change.  (It also

appears to mean KIA failed to meet CAFE unless they have banked credits.)
http://www.hispanicbusiness.com/2012/11/2/kia_hyundai_overstated_fuel_effici
ency_will.htm
"On average, the EPA found that both companies had overstated their
efficiency 
by an average of 3 per cent. For the 2012 KIA fleet, this means a downgrade 
from 27 miles per gallon (mpg) to 26 mpg. In metric system terms, it means
the 
fleet uses 9.6 litres per 100 kilometres instead of the claimed 8.7 liters."
(To save you math, the 9.6 claim should be 9.0 L/100 km, assuming the mpg 
figures are correct.)
