Millimeters rather than centimeters or meters should be used for the
default for height. Millimeters has a number of advantages even though
millimeters it may imply more precision. Use of millimeters only for height
avoids complexity and confusion.
Meters and centimeters require a deci
It is good of you to promote metric height numbers.
However, I do not like centimeter.
I want schools to stop teaching and using centimeter.
I also want schools to stop teaching inch-pound numbers.
So, I want height to be in millimeters.

I'm not sure whether centimeters or meters is my first choice, but millimeters
for human height is my third.
Since Americans aren't very metric, maybe we should look at prevailing practive

If centimeters without a decimal point is the only unit for height, I would
have no objection. If that half-inch precision is all that's needed, then OK.
If added precision is needed then millimeters is far better. Decimal points
should not be used in any case.
Automated measurement
Yes, you could automate the measurement, but humans aren't precise enough for 1
mm resolution. Most people are slightly taller in the morning when they get up
that they are by the end of the day; 1 cm resolution is appropriate, more is
"decimal dust."

Now you're talking U.S. law and regulation regarding a particular

I take exception to the expression, anti-centimeter prejudice.

Centimeters is the industry common measurement for cycling (frames) and skiingso I use them regularly. But this is like the meter vs metre argument. Who cares as long as it's not inch-foot-pounds

I agree with that. However, NIST has CLEARLY indicated that the centimeter is
OK for trade. They may feel the dekameter is fine too, in general, but in
fact, it is not OK for trade.
I believe we are talking about practice here, as the way height is stated has
ramifications in medical records
I concur. I would imagine that someday in the U.S. it will be standard
and specified practice to state a person's height only in meters for
drivers' licenses and in medical records. Or, to state a person's height
only in centimeters for drivers' licenses and in medical records.

Thanks Pat for the article reference.
The excerpt below from the article summarizes height measurement issues.
In this age of technology, especially in clinics and hospitals,
measurements for height and time of observation can easily be incorporated in
