Bill, I notice in your SI Navigator that you mention the Canadian and International editions of Time Magazine as using metric measures to some extent.
I have had a subscription for this past year to the regular U.S. edition of Time Magazine and assure you that their articles show US customary with SI-metric in parentheses. They use logical approximations when the USC is an approximation and more exact when the USC is an exact number. I've never seen any of those ridiculous tenths of a millimeter or tenths of a gram or such nonsense as that. I think The US edition of Time Magazine deserves credit for their efforts on your SI Navigator magazine tables. Norman Werling
