1 EQ: Why is the metric system used in science? What are the base units used in the metric system? What are the prefixes used in the metric system? Which metric units are used with each of the common measurements?

2 Scientists use a version of the metric system called the International System of Units (SI units), which are a set of standard units that are universal. The metric system is a system of measurement based on the number 10.

3 metric unit abbreviation  meter  liter  gram  degree Celsius  second m L g oCoC s All SI units have a base unit:

4 prefix: represents: abbreviation:  kilo- 1,000  hecto- 100  deca- 10  deci- 1/10  centi- 1/100  milli- 1/1000 k h da d c m SI units may have a prefix:
