The Moon is Metric

It is time for America to bite the bullet.


It's Official

All work done on the Moon will be done in System International (SI), also know as the Metric System. The SI term is more proper.

All design work will be done directly in SI and will not be done under other systems and then converted to SI. Such conversions are sometimes called soft metric and are unacceptable. Somebody in an office somewhere wrote that down. That is how you know it is official. Besides that, metrification is a noble cause. It leads to all people speaking the same language when it comes to measurements.
