Answer:
Standard Units of Measurement
Standard units of measurement are units of measurement that are typically used within each measurement system, like the ones we already mentioned. Because standard units of measurement are what we normally use, most measuring tools use these units. For example:
A ruler is a foot long and usually has inch and centimeter marks.
A meter stick is a meter long and usually has foot, inches, and centimeter marks.
Scales (depending on what type they are) use pounds, kilograms, ounces, or the like.
Measuring cups are normally marked in cups and ounces.
These examples don't cover them all, but you probably get the picture that common measuring instruments use standard units of measurement.
Different situations call for different units of measurement. For instance, if we want to measure the weight of a semi-truck, we would be more likely to use tons than pounds, but if we were measuring our own weight, we wouldn't even think about using tons. The more we work with standard units of measurement, the more easily we will be able to recognize which unit of measurement is appropriate for a given situation and which measuring instrument to use.
Nonstandard Units of Measurement
In a perfect world, we would always have measuring tools with standard units of measurement readily available to take a measurement. However, what do we do if we need to take a measurement and we don't have any standard measuring instruments available? Don't worry! We have a solution when this is the case! We can use nonstandard units of measurement.
Nonstandard units of measurement are units of measurement that aren't typically used. For instance, suppose we wanted to measure the distance from one wall of a room to the opposite wall. Our first instinct is to use feet, but suppose we don't have a ruler handy. This is where we can get creative.
