What does the unit decibel measure?
The ratio between two quantities, usually quantities that somehow measure power, or intensity (power / area).
What are ratios of equal quantities?
The ratio of two equal quantities is 1 .
An equation states that two quantities are what?
An equation states that the two quantities on each side of the equal sign are equal.
What is the name for multiply or divide two quantities by the same number?
If the quantities are related linearly, then the operation would mean SCALING Otherwise it is just operations on the two quantities by a constant
What is derived quantity?

What is formula for calculating watts into volts?
Watts are used to measure power, whereas volts are used to measure potential difference. These are two different quantities, and you cannot convert one into another any more than you can convert kilometres to kilograms.
What is the difference between saying that one quantity is proportional to another and saying it is equal to another?
When two quantities are proportional, it means that they change in a consistent ratio. If one quantity is equal to another, it means that they have the same value. Proportional relationships involve a constant factor, while equal relationships involve identical values.
What is the quotient of two quantities called?
The quotient of two quantities called a ratio.
What makes two quantities proportional?
Any two non-zero quantities are always proportional. If the two quantities are X and Y, they are proportional to X/Y.
A comparison of two quantities?
What is called a statement of comparing of two or more different quantities
Uses division to compare two quantities?
A ratio uses division to compare two quantities.
Why does not wattmeter measure the reactive power?
A wattmeter is designed so that it measures the supply voltage and the in-phase component of the load current. The product of these two quantities is the true power of the load.
What are ratios of equal quantities?
The ratio of two equal quantities is 1 .
What is the ratio of two quantities that change?
It is a non-linear or non-existent relationship between the two quantities.
What is a mathematical statement that says two quantities are equal?
An equation is a mathematical statement that says two quantities are equal.
