- 41.3 fm= 41.3 * 10^ -15 metre.
- 2km/hr²= 2*10^5 cm/ (3600)² = 0.015432=1.5432*10^-2
- Y= 9*10^11N/m²= 9* 10^11 * 10^3gm/s² 10^2cm =9*10^12 dyne/cm.
- Distance between sun and earth in light yr= 1.5975*10^-5. In par sec. = 4.848*10^-6.
- Work ,kinetic energy , Torque and potential energy have same dimensions as [M^1L^2T^-2].
Hope it helps.....
