Question

The ratio of SI units to CGS units of acceleration due to gravity is

• A. ${10}^2$
• B. $10$
• C. ${10}^{-1}$
• D. ${10}^{-2}$

Answer 1

The correct option is A ${10}^2$

Acceleration due to gravity $g$ is measured in $m/s^2$ in SI units.

In CGS, unit is $cm/s^2={10}^{-2}m/s^2$

So ratio of SI to CGS is $m{s}^{-2}/{10}^{-2}m{s}^{-2}={10}^2$
