What system is based on the international system of units?

S.I. is based on the meter, kilogram and second.The kilogram is defined as the mass of a lump of platinum in a vault near Paris.The second is defined as a certain number of cycles of a particular spectral line.The meter is defined as a number of wavelengths of a particular spectral line.Since c (the speed of light) is now defined to 9 digit accuracy the last two can be done by comparing the ratio of the two light frequencies.
