Have a look at the first page of this NASA publication, a free download: <http://www.nasa.gov/pdf/396782main_mf18_sumrall.pdf>. I was given that picture of four launch vehicles, so I then surfed to its online PDF to clarify the symbols.
I could guess that mT did not mean millitesla. I would not have guessed metric ton. The NASA editor apparently knew that k means x1000, but look at the goofy way a cap K is appended to numerals. This image's technical information needs a lot of repair before I can can reprint it. [End]
