Don't know where you got the 1% ....???
The difference is, from my conversion reference, 4% - or if you want to be
really picky it is 4.08%

Unfortunately, the wimpy government has been more influenced by the high
degree of cross-border trade than by the advantages of a system of
measurements based on the decimal system - rather than on an archaic
system based on the length of a monarch's pedal extremities, width of a
hand, or other equally arcane source.
You may not have noticed but, if it is a Canadian product, the SI (metric)
quantity is on every label.
You have also identified the other major 'trade based' departure from SI -
the wood products that the US needs, but is not want to pay fair value
for!
Fortunately, most products are marketed in SI units - gasoline, fuel oils,
almost(?) all automotive products, paints, a truckload of gravel, ....
and the list goes on and on. Food and wood products are the highly visible
major exceptions.
OTOH, I have yet to get in the habit of checking my weight in SI rather
than pounds. :-)
