Because it is a SYSTEM and was designed for ease of use. The accumulation of English-Imperial-American-Customary units is not a system. Example. A cubic inch of water weighs what? Versus- a cubic cm or water is a ml and weighs one gram. The best way to get to know the metric system is to NEVER covert units from inches, etc. Just use metric--it's simple! Conversion are hard and a huge bother. Science has used the metric system for a couple centuries. Many important units are defined in metric terms and nothing else.
The metric system, also known as the SI system of units, is the system most typically used in the science community.
The SI (Systeme International) units have made scientific calculations easier.
The SI unit for temperature is Kelvin.Kelvin = Celsius + 273Fahrenheit and Celsius are non SI units, however, Celsius is used in science as it is so easily converted to Kelvin.

SI units are more accurate than English system units
SI units are the international system of units used in science to ensure consistency and accuracy in measurements. Common SI units include meters for length, kilograms for mass, seconds for time, and Kelvin for temperature. These units provide a standardized framework for reporting measurements and data in scientific experiments.
SI units are used in Science Classes because they are universal and standard, and they are also easier to use because they are based no the power of ten.
The International System of Units (SI) is the most widely used system of measurement in science. It is based on seven base units, including the meter for length, the kilogram for mass, and the second for time, and is used universally in scientific research and publications.
It depends on the science.Most science normally uses the SI (international system) - the same system which is used in most countries of the world in everyday life as well. Theoretical particle physics often uses another system, called the system of natural units, or Planck units. Many sciences use at least SOME non-SI units; for example, in particle physics, even if the SI is used most of the time, energies are usually expressed in eV. And in most areas of science, non-SI time units (i.e., units other than seconds) are used.
In science the International System (SI) of unit is used. This is a metric system.
The metric system, also known as the SI system of units, is the system most typically used in the science community.
In engineering and science, a system of units called SI is used. The same units are used worldwide in most countries outside of the United States, except that in practice, some non-SI units are used as well (for example, hours and days instead seconds, and the degree Celsius instead of Kelvin).
The same units can be used for any type of energy - and in modern science, the same units ARE used. For example, the SI unit for energy is the joule.
The full form of SI unit in science is "International System of Units." It is the modern form of the metric system and is the most widely used system of measurement in the world, encompassing seven base units.
The principal SI units used to derive all other SI units are the base SI units. These are the units for physical quantities such as length, time, mass, electric current, temperature, amount of substance, and luminous intensity.
Perhaps you refer to the seven basic SI units? The number and choice of base units depends on the system used. In the case of SI, you can find the base units here: http://en.wikipedia.org/wiki/SI_base_unit
