anonymous one year ago I need help with feeling in the missing boxes. For example mass= weight, volume(liquids), volume(solids) and weight= pound(lb) & fluid ounce(floz) . I need help finding 3 words for kilograms.

For weight, we know from Newton's laws that F=ma. What does this actually mean without numbers? Substituting a for the gravitational acceleration constant, we then have F=mg. Looking at the units, we have $mass*acceleration=kg*\frac{ m }{ s^2 }$ This combined unit of measurement is also called a Newton (N), a measurement of force. All forces in the metric system are denoted by N, whereas in the U.S. system it is denoted as pounds (lb) (when deriving pounds, we use the same process F=ma but the units for the mass and acceleration are in the U.S. system) The unit for a liquid volume is termed liter, and is broken down in SI base units as 0.001m^3. In other words, one liter is the volume of a liquid cube with side lengths of 10cm. The unit for a solid volume is simply the length cubed. ex: 10m^3 or 20mm^3. Sorry if this was more complicated than what you were looking for. I just think sometimes it's helpful to understand some logical thinking in case you forget what the units are.

Also, the imperial (U.S.) system for mass is the slug. In all my 12 years of public schooling, I've never had to deal with units of slugs.
