I wanted to say that by default, \tfa = 1.2 times \tf size, tfb is 1.44
times \tf size, tfc = 1.728 times \tf size, tfd = 2.074 times \tf size,
and tfe = 2.488 times \tf size. So you can always use
(in a 10 point document)
\definefont[chapterfont][Sans sa 1.728]
\setuphead[chapter][style=chapterfont]

The default values of \tfa etc can be changed by \definefont. If these
values have not been changed, then you can use:
\definefont[chapterfont][Sans sa \magfactor3]
\setuphead[chapter][style=chapterfont]
\magfactor is defined in font-ini.tex as
\def\magfactor#1%
{\ifcase#1 1.000\or1.200\or1.440\or1.728\or2.074\or2.488\or1\fi}
so \magfactor 3 is equal to \tfc in size. You can also use a more plain
TeX like syntax as
\definefont[chapterfont][Sans scaled \magstep3]
where \magstep is defined in font-ini.tex as
\def\magstep#1%
{\ifcase#1 [EMAIL PROTECTED]@m\fi}
