​

Answer 1

Answer:

$\fbox{Answer-}$

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.

non standard units of measurement are units of measurement that aren't typically used, such as a pencil, an arm, a toothpick, or a shoe.
