Question

How many grams are there in a pound?

Answer 1

Hint: The pound is the unit of mass which is used in the United States. It is represented by the symbol lbs. So, we have to determine how many grams are approximately there in one pound. Both pounds and grams are units of mass and can be changed into one another.

Complete step by step answer:
In the given question, we are required to convert $1$ pounds in grams. Since the pounds and grams 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 $1$ kilogram $ = 2.205$ pounds.
But a kilogram consists of a thousand grams.
So, we substitute the value of a kilometer in the terms of grams. Hence, we get,
\[ \Rightarrow 1000\,g = 2.205\,lb\]

Now, we divide both sides of the above equation to find the value of a pound in terms of grams. So, we get,
\[ \Rightarrow 1\,lb = \dfrac{{1000}}{{2.205}}\,g\]
Doing the division, we get,
\[ \therefore 1\,lb = 453.5\,g\]

So, there are a total of \[453.5\] grams in a pound approximately.

Note: The basic conversion rate from pounds to grams is essential as it helps in exchanging the things internationally 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.
