The density of wood is 0.5 g/cc in the CGS system of units. The corresponding value in MKS units is:

Question

Accepted Answer

To convert the density from the CGS system ($g/cm^3$ or $g/cc$) to the MKS (SI) system ($kg/m^3$), we use the standard conversion factors for mass and length.

1.  **Conversion Factors:**
    *   Mass: $1 	ext{ g} = 10^{-3} 	ext{ kg}$.
    *   Volume: $1 	ext{ cm} = 10^{-2} 	ext{ m}$, so $1 	ext{ cm}^3 = (10^{-2} 	ext{ m})^3 = 10^{-6} 	ext{ m}^3$.

2.  **Derived Conversion for Density:**
    $$ 1 \frac{	ext{g}}{	ext{cm}^3} = \frac{10^{-3} 	ext{ kg}}{10^{-6} 	ext{ m}^3} = 10^3 \frac{	ext{kg}}{	ext{m}^3} = 1000 \frac{	ext{kg}}{	ext{m}^3} $$
    This direct conversion is listed in the NCERT Appendices .

3.  **Calculation:**
    Given density $= 0.5 	ext{ g/cc}$.
    $$ 0.5 	imes 1000 = 500 	ext{ kg/m}^3 $$

Thus, the numerical value in MKS units is 500.
