Dear Ms. Bohren,
I am looking at the labels the EPA is proposing for
fuel economy for vehicles.
I find no mention of metric units for these labels.
It is likely that labels, at this time, are not an effective
place to start using metric units. So, I back up to see if your
work can give a background to the EPA for use of metric units.
What units do you use at NCVECS?
What do you see as the future for no longer using
inch-pound units?
Do you know where to look for what metric units are
suitable for your work?
Please tell me about your use of units.
Thanks.
