Brief instructions and example showing how to convert between units (say, from mi to m) using conversion ratios. Converting from one dimensional unit to another is often somewhat complex and being able to perform such conversions is an important skill to acquire. The factor-label method, also known as the unit-factor method or dimensional analysis, is a widely used approach for performing such conversions

Well organized tables showing what the number prefixesâ€”micro, nano, mega, giga, etcâ€”mean and how to replace them with numbers. Note: gigabyte, megabyte, kilobyte, use a slightly different meaning for the prefixes. This can be a little confusing. The Wikipedia article has a nice little discussion of the difference between that and the SI usage.

Well organized tables showing conversion factors for a lot of different units. For example, if you need to know * how many feet in one kilometer * how many Newtons are in one pound * how many cubic feet are in a cubic meter Look in the table for Length for the first, the table for Force for the second, and the table for Volume, for the third, and so on.
