Question

How do you convert $ 8 $ milliliters to fluid ounces?

Answer 1

Hint: We all know the basic conversion that is one fluid ounce is equal to $ 29.6mL $ To acquire the conversion of milliliters to fluid ounces we just need multiply the milliliters value by $ 0.03709 $ or by simply divide it by $ 29.6mL $
Milliliters is a metric system mass unit 1ml = 0.03709fluid ounces. The symbol is "ml".
Milliliters to Fluid Ounces formula :
 $ 1\text{ }fluid\text{ }ounces\text{ }=\text{ }\dfrac{milliliters}{0.03709} $
 $ 1\text{ }fluid\text{ }ounces\text{ }=\text{ }\dfrac{milliliters}{26.96} $

Complete step by step solution:
We know that the if we meant $ 8mL $ to fluid ounces we can do using following steps
We have to recall that multiplying any number by $ 1 $ gives us exactly the same number, the basic conversion.
Then we have to use the conversion that we have given to build number or something that are equal to $ 1 $
Likewise if we divide both the side by $ 1mL $ we get;
 $ 1\text{ }=\text{ }\dfrac{0.034\text{ }fl\text{ }oz}{1mL} $
Now when we multiply the $ 8mL $ by that $ '1' $ we had earlier and if we pick the correct way to arrange $ '1' $ ratio the subsequent unit of mL would be on bottom. Units are cancelled in the same exact way that we have 'x' in a normal mathematical equation. So that we have units of mL that are cancelled and were again left with just fl. oz. on top. This is exactly the conversion of millimeters to fluid ounces.
 $ 1\text{ }fluid\text{ }ounce\text{ }=\text{ }29.6\text{ }mL $ and the acquired
 $ \dfrac{8mL}{29.6\dfrac{mL}{fl.oz}}=~\dfrac{4}{15fl.oz} $

Note:
Conversion factors are required because while doing the numerical we have different values in different units and while doing the calculation all the units should be the same, so we have to either multiply or by dividing the given value with unit of conversion value so that to convert their unit from one form to another vice versa.
