There are several reasons. Some of them are:
1. They are internationally agreed as standard. Not like a gallon which can mean one amount in the US and another in the UK.
2. Orders of magnitude for the same measure are related by simple decimal conversions and only a handful of prefices are required (although there are a lot more). By way of contrast, the Imperial system uses:
and so on, and on and on. The decimal structure also makes it very simple to use scientific notation for small and large quantities.
3. It is used by most people in the world. The main recalcitrant countries are USA, Liberia and Myanmar. Even in the US, scientists normally use SI. When they don't they have disasters like the one that trashed NASA's Mars Climate Orbiter at no small cost!
4. There are many simple relations from measures for one characteristic to another. For example, the SI unit of length is 1 metre. 100 square metres = 1 are, the unit for area. 1 cubic metre = 1000 litres, the unit for volume.
Standard measurements make it easier for everyone to know what that measurement means. The metric system, which is the standard system used by scientists, is specifically designed to be easy to use. The English system is much more complicated, mathematically.

who invented the english measurements
900cc = 900 cubic centimeters = 0.9 liter This is an English measurement. Britain now uses the International Standard measurement units. If we go back in time, 900 cubic centimeter = 1.5837785878 pint [UK].

It is easier to under stand than the English system. Every thing is based on 100's.
It was recognised that there needed to be an internationally common scientific measurement system and the international scientific community concensus was that it should be the SI system.
The International System of units uses celsius as the measurement of temperature. It is called the SI system of measurement. The International Union of Pure and Applied Chemists use Kelvin as the official measurement of temperature.

Established in 1960 by the international agreement, the "Metric System" is the international standard of measurement.

The SI (International System of Units), and the Metric System.
SI stands (in French) for Système international d'unités, the International System of Units [of measurement].
International System, SI. (from Lè Système International d' Unités).
The base SI unit of distance is the meter.
