The convert/radians function converts an expression from degrees to radians by multiplying it by Pi/180.

The expression must be of degree 1 in the indeterminate degrees.

$\mathrm{convert}\left(90\mathrm{degrees}\,\mathrm{radians}\right)$

$\frac{\mathrm{\pi }}{2}$

$\mathrm{convert}\left(15\mathrm{degrees}\,\mathrm{radians}\right)$

$\frac{\mathrm{\pi }}{12}$

$\mathrm{convert}\left(34\mathrm{degrees}\,\mathrm{radians}\right)$

$\frac{17\mathrm{\pi }}{90}$

$\mathrm{evalf}\left(\mathrm{convert}\left(34\mathrm{degrees}\,\mathrm{radians}\right)\right)$
