1. They are internationally agreed as standard. Not like a gallon which can mean one amount in the US and different amount in the UK.
2. Orders of magnitude for measuring the same attribute are related by simple multiples or fractions of powers of ten conversions and only a handful of prefices are required (although there are a lot more available for very big and very small amounts). By way of contrast, the Imperial system uses:
There are only three countries that have not officially adopted the metric system as their system of measurement: the United States, Liberia, and Myanmar.
-- Meter -- Kilogram -- Second -- Coulomb
The metric system is based on three principles: the meter as the unit of length, the gram as the unit of mass, and the liter as the unit of volume. All other units in the metric system are derived from these base units using prefixes to denote multiples or fractions.
Meters, liters, kilograms.
THE METRIC SYSTEM WONDERLAND or THE WONDERS OF THE METRIC SYSTEM
90% of the world deals in the metric system that in itself is the biggest advantage.
We learned the metric system in math today.
There are only three countries that have not officially adopted the metric system as their system of measurement: the United States, Liberia, and Myanmar.

You dont have to use your head you can just use it instead.
Inches, feet, and pounds
The units are: -- Kilogram -- Meter -- Second. All of the other units in the metric system are fractions, multiples, or combinations of these three.
As of 2016, the only countries that do not use the metric system are the US, Burma and Liberia. All other countries use the metric system.
Only three countries still cling to the "English" system, whereas the whole world uses metric. The SI units were established in 1960 as part of a review of the metric system used at the time; it uses metric units because it is the current version of the metric system.
