Question

How many ounces are there in $2\,lbs$?

Answer 1

Hint: The ounces and pound are the units for measuring mass which are used in the United States. Pound is represented by the symbol lbs. So, we have to determine how many ounces are approximately there in two pound of weight. Both pounds and ounces are units of mass and can be changed into one another using a basic conversion rate.

Complete step by step solution:
In the given question, we are required to convert $2\,lbs$ into ounces.
Since the pounds and ounces belong to two different systems of units for the same physical quantity, that is mass. So, they can be converted into one another through the unitary method with the help of basic conversion.
In the unitary method, we can first find the value of one unit and then subsequently multiply the value of one unit by the desired number.
We know that $1$ pound $ = 16$ ounces.
So, we first write the conversion in the lbs. So,
$1\,lbs = 16\,$ounces
Now, we multiply both sides of the above equation to find the value of two pounds in terms of ounces. So, we get,
\[ \Rightarrow 1 \times 2\,lbs = 16 \times 2\] ounces
Doing the calculations, we get,
\[ \Rightarrow 1 \times 2\,lbs = 32\] ounces.
Therefore, there are a total of \[32\] ounces in $2\,lbs$.

Note:
The basic conversion rate from pounds to ounces is essential as it helps in exchanging the things as both the system of units can convey the same mass. Units should always be written once the final answer has been evaluated after writing the numbers as only the numbers don’t make any sense. We can multiply or divide both sides of the equation by the same number using the method of transposition to find the conversion of a specific number of quantities from one unit to another.
