created prefixes for good reasons, so the argument is not with me, but
with those people
The new common core standards in mathematics do not allow conversations between

The Earth's polar circumference is 39.94 Mm. (It was exactly 40 Mm
from 1791 to 1875, but the definition of the metre was changed; see
metre).
The distance from Amsterdam to Marseille is approximately 1 Mm.
The Earth's
I suggest you instead use the Wikipedia articles on the metre and history of
the metre. Link to the first is:

It has the advantage of actually using references. The other one might have
been written by ACWM or BWMA as they both like to assert the meter was
