There are 0.45 kg in a pound. There are 16 oz in a pound. How many grams are in an oz?

Answer :

From the information given

1 pound = 0.45kg

Recall that 1 kg = 1000 gram

0.45 kg = 0.45 x 1000 = 450g

Hence, 1 pound = 450g ----------------------------------(1)

There are 16 Oz in a pound.

This means 1 pound = 16 Oz------------------------------(2)

Since 1 pound = 450g

and 1 pound = 16 Oz

It implies 450g = 16 Oz

Divide both sides by 16

[tex]\begin{gathered} \frac{450g}{16}=\frac{16\text{ Oz}}{16} \\ 28.125g=\text{ 1 Oz} \\ \text{Hence, 1 Oz = 28.125g} \\ \text{ The answer is 28.125g} \end{gathered}[/tex]

Final answer:

To find out how many grams are in an ounce, we need to convert pounds to grams (1 pound = 453.6 grams) first. Then, divide this amount by the number of ounces in a pound (16), which gives approximately 28.35 grams in an ounce.

Explanation:

In this question, we are dealing with conversion of units of mass between the metric system and the Imperial system. The key information we need from the question is that 1 lb is equivalent to approximately 0.4536 kg and that 1 lb is equivalent to 16 oz. Therefore, to find out how many grams (g) are in an ounce (oz), we will need to follow these steps:

  1. Convert our pounds (lb) to grams (g). Since 1 lb = 0.4536 kg and 1 kg = 1000 g, we can see that 1 lb = 0.4536 * 1000 = 453.6 g.
  2. Knowing that 1 lb = 16 oz, we can calculate 1 oz in grams by dividing the number of grams in a pound by 16. So, 453.6 g / 16 = 28.35 g.

So, there are approximately 28.35 grams in an ounce.
