There following are the main reasons.

  1. To get internationally agreed standards: unlike a gallon which was one measure in the US and a different measure elsewhere.
  2. To base the measurement units on sensible rather than arbitrary measures. Originally, a yard was the length of a man's girdle (or belt). Then in the 12th Century, Henry I of England declared it as the distance from his nose to the thumb of his out-stretched arm.
  3. Create close relationships between units for different measures: for example, the unit for acceleration was one unit of distance divided by the square of the unit of time; the unit for force was a unit of mass times a unit of acceleration; pressure was unit of force divided by unit of area.
  4. Define larger and smaller units by using factors and multiples of 10 (or 1000), and use prefices to move up or down the scale. By contrast the old system had :
  • 2 pints in a quart
  • 3 feet in a yard
  • 4 quarts in a gallon
  • 6 feet in a fathom
  • 8 furlongs in a mile
  • 9 square feet in a square yard
  • 12 inches in a foot
  • 14 pounds in a stone
  • 16 ounces in a pound
  • and so on.

Standardization allows people in different places and different countries to use the same units, avoid mistakes, understand each other more easily.

The common base 10 of all units allows for easier and more accurate calculations without cumbersome conversion factors.

The ONLY purpose is for "communication" as it relates to an acceptable "standard"

*********************Answer*****************

It's because it's was created to be easy to use because it's based in 10's. It's very good at measuring very large or very small things. This is why it's standard in sciences. All scientific publications I have seen are in metric when measurements are needed. Try to measure wavelength or atom size in inches. I don't even know what are the smallest units in US/Imperial system.

It's also standard in most countries in the world so communications/trades are easier. When you sell your products to Another Country, you better use the system of measurement they understand. As it is now, most US products typically have labels in both systems. Car engine sizes now are commonly measured in Liter or cubic centimeter (cc). Some American cars (typically muscle cars) are sometime referred in cubic inches, but that's a minority. Most cars, even American brand, are now made in metrics due to global markets and supplies.

Standardization. The metric system is much older, but the SI units are simply the newest official standard.

Metric units were developed to replace the ridiculously inconvenient units that were in common use at the time. The metric system wasn't clearly "better" in any way except one: there was only one basic length unit, and other "units" were derived from it using powers of ten only. It's therefore trivial to convert centimetres to kilometres, even in your head, while converting inches to furlongs is not something for the faint of heart ... even if you actually know what a furlong is. SI came about as scientists and tradesmen in various countries saw the utility of this new system, particularly since if you're switching to a new system anyway, you might as well switch to one that someone else is using (prior to this, a "yard" or "foot" in one country might be a different length than a "yard" or "foot" in another country). It's good for scientists, because then they don't have to specify WHICH "foot" they're talking about. It's good for tradesmen, because then a supplier of fabric (in, say, Italy) and purchaser (in Germany) agree on how big a particular piece of material is, rather than each of them using their own country's units.

it has done to have unified system of units all over the world. so that we do have a unique system of measurement that is accepted world wide and is used by all the countries.

The SI system from the French Système international d'unités was developed in 1960.
