Hint: Ounce is a unit of measurement in the imperial system of units. It is mostly used in the measurement of mass and weight. It is an empirical value derived from the customary measurement system used in Britain and its associative regions. It is the smallest unit of mass in this system.
Sixteen Ounces is equal to one pound. For better understanding, let us compare this with our metric system.
One pound is approximately equal to 0.454 grams.
Complete Step by Step Solution:
Before going into the problem, let us discuss some of the important units of mass used in various systems of measurements.
The metric system which is used predominantly in France is the most widely accepted measurement system nowadays. It is also known as the International System of units, shortly SI units. Most countries including India have adapted this system due to its convenience. But some countries are still in the conversion phase from their customary system to the metric system.
The mass unit ounce is still used in measuring precious metals like gold, platinum, etc. It is known that thirteen ounces is equal to one pound.
$\Rightarrow 16\text{ ounces}=1\text{ pound}$ ……(1)
In the metric system, Kilogram is the unit of mass. And one kilogram of mass is equal to 2.205 pounds.
The given mass is equal to 40 ounces.
Let us find out the conversion factor
Therefore from equation (1)
$\Rightarrow \text{1 ounce}=\dfrac{1}{16}\text{ pounds}$
$\Rightarrow \text{40 ounces}=\text{40 }\!\!\times\!\!\text{ }\dfrac{\text{1}}{\text{16}}\text{ pounds}=\text{2}\text{.5 pounds}$
The symbol of the abbreviation of Ounce is Oz and for pound, it is lb.
Hence,
$\Rightarrow \text{40 Oz}=\text{2}\text{.5 lb}$
Note:
In the Imperial systems of units, the force is denoted as pound-force (lbf). It should not be confused with the unit of the mass pound (lb). One pound-force (lbf) is approximately equal to the 4.448 N in SI units. Another similar quantity that is different from mass pound units is foot-pound which is a unit of energy.
