the United States is the only place that still uses the English system. everywhere else uses the Metric. thus, it would make more sense to use the Metric system.
Actually, any sensible person prefers the metric units, since you don't have to carry a bunch of wildly different conversion factors around in your head... it's all based on multiples of ten, and lots of the units are related (for example, a liter is the volume of a cube 0.1 meters on a side). The only reason some people don't like them is because they don't know them, while they (think they) know the English units. Most of the time they really don't... most people are doing good if they can estimate a distance or weight of an unfamiliar object closer than a factor of two.
An additional advantage of the metric system (specifically, SI) is that it's the same everywhere. Word like "foot", "inch", "pound" and the like were used for different measurements in different countries, so for example an Imperial (i.e., UK) gallon is a different volume than a US gallon (it's larger by about 20%, so a US "quart" is about the same as an Imperial "fifth"); if you're dealing in international trade, understanding this can be very important. However, a liter is a liter everywhere.

1) It is an international standard, so all scientists use the same measurements. For comparison, for example, different countries have different definitions of a pound. 2) Calculations are easier, because of the decimal prefixes.
Apart from a couple of less advanced countries and (including?!) the US, all countries use the metric system. Since it is based on multiples of tens, calculations are simpler. Also, there are simpler links between measures for different attributes, for example between mass and volume.
You have your choice. If you like the metric system, measure your ping pong table in meters. If you prefer the English system, measure your ping pong table in feet.
Mainly to use an accepted standard (scientists all over the world use the same units). Also, it is easier to do calculations in metric units.
Because exponential or scientific notation needs less digits for very large numbers and metric units are preferred because they are in multiples of 10 thus avoiding mistaken calculations.
