Hello, after being away for a long while I come back on the forum.... with a question: can anyone tell me how one passes from Gaussian units to MKSA and vice-versa? Or does anyone know a good book (not the jacksons, it's not clear enough to me) or a good site?
Thanks very much.

I found two sites which might help.

MKS is the system of units based on measuring lengths in meters, mass in kilograms, and time in seconds. MKS is generally used in engineering and beginning physics, where the so-called cgs system (based on the centimeter, gram, and second) is commonly used in theoretic physics. The most familiar units of electricity and magnetism (ohm, farad, coulomb, etc.) are MKS units.

The following table summarizes common quantities and their units in both MKS and cgs. Table available at:

and one that gives

In MKS, these become

thanks for the quick answer, but now I do not have time to check the site I'll look at it tomorrow and will tell you then if it's what i was looking for.
