As others state the "conversion", does, I believe need some intelligence and, not the least, some "contextualization". Aside of the computer-algebra systems (Maple, Mathematica, soon MuPad, GAP, Yacas) which generate MathML-content at least from within their human-readable syntax, I would note two more things (not really inputting MathML-presentation): -> the QMath processor (start at http://www.matracas.org/) is a tool which accepts a textual syntax closer to that of these computer-algebra-systems and creates OpenMath out of it (which then not too hard to convert into MathML-content). QMath is extensible and can, with some work (the contextualization), be used to convert formulae in a TeX source into formulae in OpenMath -> the efforts of the team of Stephen Watt at ORCCA (Londong, Ontario) which have a LaTeX to MathML trying to convert most possible LaTeX into some semantic encoding (which gets enriched as it goes), producing the conversion-stylesheets to MathML-presentation as well And I think and wish I had forgotten others.
