system ( units )
| | | |
SI units - correct answer -International System of units based on the metric
| | | | | | | | | | | |
system and on units derived from the metric system
| | | | | | | | |
volume - correct answer -is the amount of three - dimensional space occupied
| | | | | | | | | | | |
by a substance . The fundamental unit of volume in the SI system is based on
| | | | | | | | | | | | | | | |
the volume of a cube that measures meter in each of the three directions
| | | | | | | | | | | | | |
mass - correct answer -which can be defined as the quantity of matter present
| | | | | | | | | | | | |
in an object .

, significant figures - correct answer -The certain digits and the first uncertain
| | | | | | | | | | |
digit of a measurement
| | | |
rounding off - correct answer -When you perform a calculation on your
| | | | | | | | | | |
calculator , the number of digits displayed is usually greater than the number
| | | | | | | | | | | | |
of significant figures that the result should possess . So you must

conversion factors - correct answer -is a ratio of the two parts of the statement
| | | | | | | | | | | | | |
that relates the two units
| | | | |
Equivalence statement - correct answer -A statement that relates different
| | | | | | | | |
units of measurement
| | |
Dimensional analysis - correct answer -The changing from one unit to another
| | | | | | | | | | |
via conversion factors that are based on the equivalence statements between
