There are various font packages, e.g, times and helvetica available for Latex. Each package is a family of fonts with one member being a roman font and another a sans-serif.
If you want to put your document in a sans-serif font, such as for
a grant proposal, you could use the sans-serif font in the times package,
which happens to be the helvetica font (like Arial in Windows). To
do this for a whole document, insert the following in the preamble
of your document:
\renewcommand{\familydefault}{\sfdefault}
Note that just using the helvetica package without specifying use of a sans-serif font will not accomplish what you want.
