Hi,
May I know if the general GRE tests units?
I am familiar with SI units, but am totally new to units like yards, feet, etc, which I understand is used more often in the US.
So, do we have to memorize stuff like 1 mile= 1760 yards= 5280 feet ?
If so, what are the more common units in the GRE (general)?
Thanks.

Re: Units in General GRE
I wouldn't worry about it too much, but I suppose it wouldn't hurt to know some of the more common ones if only for your own benefit, especially if you plan on living/studying here in the U.S. for a length of time.
From my experience I don't recall any problems where conversions were necessary, whether it was SI <> Imperial, Imperial > Imperial, or SI > SI. This is not to say you won't see any yourself, however.

I didn't see any questions on unit conversions on my test at all.
I think "12 inches = 1 foot" could maybe be considered one of the "common" ones. I don't think any other imperial unit conversion would be considered common. Maybe "16 ounces = 1 pound", but I doubt it.
As far as reallife here in the states goes, these are the conversions in order of importance:
Top five:
12 in = 1 ft
5280 ft = 1 mi
16 oz = 1 pound
8 fl. oz = 1 cup
and
3 ft = 1 yrd (only for American Football fans )
Temperature:
0 deg C = 32 deg F (freezing point of water)
100 deg C = 212 deg F (boiling point of water)
F<>C is linear.
So from these two points anyone on a site called Mathematics GRE should be able to come up with the formula for C to F in a couple seconds in their head: F=(9/5)C+32.
I personally choose to remember that the slope of the transformation is 9/5, and the freezing point (yintercept) is 32. I think it's easier to remember the number 9/5 than the number 212, but only because I grew up with it. Nowadays it's easy to remember 212, though, because it's the area code for Manhattan. So, you just have to remember that "water boils in Hell's Kitchen" and know the area code for Manhattan like I do, lol .
Less common measurements:
2000 pounds = 1 ton
4 cups = 1 quart
4 quarts = 1 gallon
(For "quart" think "quatre=four", as in: "a quart is four times a cup and a quarter of a gallon"gallon and cup being the two most common volume measurements in America)
2 cups = 1 pint
(For pint, think "p as in pound", as in one pound of water, a pound of water is 16 fl. oz, and 16 fl. oz is 2 cups. So a pint is two cups.)
Questions may involve units of measurement such as English units or metric units. If an answer to a question requires converting one unit of measurement to another, then the relationship between the units is provided, unless the relationship is a
common one, such as minutes to hours, or centimeters to
meters.
