Buff Mokey Mouse - the american metric system is weird

And NASA uses the Metric System, and all the scientists do, only common people are still living with the old system for mundane tasks.

Using imperial in science is just adding an extra layer of possibility to screw up.
Is it possible to imperial exclusively and land the probe properly? Sure, but why tho?
Both systems are arbitrary but if the majority of scientific community supports one, there's no real purpose to use the other.
