At least one Pixar film used metric. Or at least in one of the extras on the
DVD.
Buried in the special features on the DVD for "The Incredibles" is a page
listing attributes and
characteristics of various superheroes in the "Incredibles" universe, some
mentioned in the film,
others not. What was surprising (for an American production) was that all
measurements in this
section were given in metric. For example, Elastigirl's maximum stretch
distance is given as 30 m
and minimum thickness as 1 mm. Assuming that it's mostly young people who
would be likely to be
exploring the special features of the DVD, I think that this bodes well for the
next generation.
Let's hope it becomes a pattern. I wonder if any other American cartoons or
comic books have made
an effort to use metric?
It's also worth noting that this area of the DVD was supposed to be a secret
NSA (National Super
Agency) file. So, at least in fiction, US government agencies are complying
with Congress's
directive that they use the metric system as their primary system of units. :-)
