#-3.5pirad#

Explanation:

To convert degrees to radians, multiply by #1/1# in radians over degrees:
#(2pi)/360# (Each measure is equal to a full circle).
#-630*(2pi)/360=-3.5pirad#

A circle is #360# degrees, also known as #2pi# radians. So #-630^circ# is

#-630^circ times {2 pi}/{360^circ} = -{7 pi}/2 # radians.

Explanation:

It's an absurd system designed to confuse students when #-7/4# of a circle is #-7/2# of the circle constant.
