Problem

A solid metal disc has a moment of inertia I=2.0×10−4 kg m2I = 2.0 \times 10^{-4}\,\text{kg}\,\text{m}^2 about its central axis. (a) Convert this value into CGS units (g cm2\text{g}\,\text{cm}^2). Show every step of your working, including all unit conversions used. (b) Convert your CGS result back to SI units and verify that you recover the original value, thereby confirming the consistency of your conversion.
