This is a useful quantity, but it is a division into the time unit. However the SI unit of the mass is kilogram. ![]() These derived units are very useful to quote as measurements, but they are not fundamental as they come from fundamental units.įor example, frequency is the number of times something happens per unit of time. Of course, you can use units such as centimeters (cm), millimeters (mm), etc. There are many quantities scientists measure that come from the base units. mole (mol) - unit of the amount of substance DISCLAIMER: These example sentences appear in various news sources and books to reflect the usage of the word mass unit.
