How can the answer be improved?SI Units: Mass. The kilogram is the SI base unit of mass and is equal to the mass of the international prototype of the kilogram, a platinumiridium standard that is kept at the International Bureau of Weights and Measures (BIPM). The primary standard of mass for mass units si system

The prefixes attached to metric units carry the same meaning for all base units. The metric system is based upon powers of ten, which is convenient because: A measurement in the metric system that is represented by a rational number remains a rational number after metric unit conversion. (For example, 250 mm 25 cm. 25 m).

SI base unit. The International System of Units (SI) defines seven units of measure as a basic set from which all other SI units can be derived. The SI base units and their physical quantities are the metre for measurement of length, the kilogram for mass, the second for time, the ampere for electric current, In the SI system, the base unit for mass is kilogram. The SI system is the latest and current version of the metric system. Previous versions included the mksA system and the cgsA system. **mass units si system** length(meters), mass (grams), and time (seconds) This answer is incorrect. The correct answer is as follows: The SI system comprises seven BASE units and numerous DERIVED units which are

International System of Units: International System of Units (SI), international decimal system of weights and measures derived from and extending the metric system of units. SI has seven basic units, from which others are derived: the second, the meter, the *mass units si system*
