Necessity of selecting some units as fundamental units?
Selecting fundamental units is necessary because they serve as the foundation for all other units in a system of measurement. By defining a set of fundamental units, we can create a consistent and standardized way to quantify physical quantities. This ensures that measurements across different contexts and locations are uniform and easily comparable.
SI units are based on multiples of what?
SI is a base 10 standardized system
What many standardized units of measurement were once based on?
ancient worldwide standards
Do SI systems vary from county to country?
No. That would defeat the purpose of standardized units.
Briefly describe why standardized units are used to compare values that are measured using different scales different units or different populations?
BCUZ
What does it take to become an air conditioning contractor?
In order to become a contractor, education and training are needed. A degree or certification in HVAC is necessary, along with experience in working with these types of units.
what are non standardized units of measurements?
Some units include the "hand" (horses) and the "span" (great span) originally equal to half of a Roman cubit.
Why did scientists agree to use the SI units worldwide instead of the units common at their locations?

Why is it necessary to have fractional units?
Not all magnitudes in nature come in integer units.
Why did scientists agree to use 1 system of measurements?
Scientists agreed to use the International System of Units (SI) to promote consistency and facilitate collaboration among researchers worldwide. By using a standardized system, it ensures accurate and clear communication in scientific research and everyday applications.
If something on a united kingdom website says a container holds 3 measures of milk how much is that in standardized units?
6
Units of time that are not based upon astronomical movements?
Units of time that are not based on astronomical movements include the second, minute, hour, and day. These units are widely used for measuring time intervals and have been standardized for practical purposes.
