Metric
No it is not. It is the metric system invented by the French which based on powers of ten. And it is the Empirical system, not the English system.
A decimal system; but probable you think to metric system.
Yes.
The SI system is based on multiples (and divisions) of ten. There are seven base units, all others are derived from these.
The metric system is used by scientists because it is based on factors of ten. This makes it easy to convert from one unit of measurement to another.
The metric, or SI system of measurement is based on units which, in most cases, are related to larger or smaller units by multiples or factors of ten. The exception is time where the factors are 60.
The metric system is used worldwide and is the standard system of measurement in most countries of the world. It is simple to use because it is based on units of ten.
The metric system of measurement is based on a multiplication factor of 10. This means that each unit within the system is either 10 times smaller or larger than the unit above or below it. This system makes conversions between different units easy and consistent.
The metric system
The English system is based on arbitrary numbers and measurements, such as 12, 36, and 5,280. The Metric system - every aspect of it - is based on even multiples of ten, both going upward, and going downward. Just ten. Nothing else.
Units with divisions that are powers of ten are called metric units. This system of measurement makes it easier to convert between different units by simply moving the decimal point. Examples include meters, grams, and liters.
