Answer:
SI units are useful because they are all related by multiples of 10.
Step-by-step explanation:
International System of Units (abbreviated SI) is a system of measurement units, which is used almost everywhere in the world.
A unit system is a set of units of consistent, standard and uniform measurement. In other words, a unit system is a set of units (grouped and formally defined) that is used as a standard. Normally, in a system of units, few basic units are defined and from these several derived units are defined.
The International System of Units defines seven basic units, also called fundamental units, which define the corresponding fundamental physical quantities, chosen by convention, and which allow to express any physical quantity in terms or as a combination of them. The other units are obtained by combining the basic units.
The basic units of this system are:
- Length-meter (m)
- Mass-kilogram (kg)
- Time- second (s)
- Electric current intensity - ampere (A)
- Temperature - Kelvin (K)
- Amount of substance - mol (mol)
- Light intensity - candela (cd)
The SI is based on the metric system, which is a system of units that are related to each other by multiples or submultiples of 10.
Then, SI units are useful because they are all related by multiples of 10.
