Hi phynessa33,

Unit conversion is certainly something that you will have to deal with in the Quant section of the GMAT (and sometimes in IR section). You are expected to know certain 'standard' units, such as days --> hours --> minutes --> seconds and dollars --> cents ($1.00 = 100 cents). In certain prompts, information on specific types of measure are included in the question (for example 1 mile = 5,280 feet or 1 meter = 100 centimeters is information that many people don't necessarily know, so a question that REQUIRES that type of conversion will often include the needed equation).

If you wanted to familiarize yourself with some additional measurements, then you might find it useful to know:
1 yard = 3 feet
1 foot = 12 inches
1 kilometer = 1000 meters
1 meter = 100 centimeters = 1000 millimeters

GMAT assassins aren't born, they're made,

The GMAT will assume that you know units that are globally standard:
TIME: seconds --> minutes --> hours --> days --> months. (e.g. a problem that states "in each month last year" will expect you to know that there are 12 months).
MONEY: 100 cents --> dollar. Ok, US currency isn't really a global standard, but they assume everyone knows this. They won't ask about fractions of other currency.

For other measurements, the GMAT will NOT require you to know any non-metric systems. You will see problems written in Imperial measurements (miles, inches, degrees Fahrenheit, etc), but if you're being asked to convert from one to the other, the GMAT will give you the formula for conversion, as Rich mentioned. They'll likely even give you the conversions for metric: grams to kilograms, etc.

Besides knowing your metric system prefixes, I wouldn't bother memorizing any unit conversions.
