Hello there! As an expert in the field of currency and coinage, I'm here to provide you with a detailed and accurate answer to your question. Let's delve into the specifics of U.S. currency to understand how many quarters it would take to make $20.

Firstly, it's important to clarify what a quarter is. In the United States, a quarter is a coin that is worth 25 cents, or one-fourth of a dollar. To determine how many quarters are needed to make $20, we'll need to perform a simple calculation.

**Step 1: Understanding the Value of a Quarter**
A single quarter is valued at 25 cents. To convert this to dollars, we divide by 100 (since there are 100 cents in a dollar). So, a quarter is equal to $0.25.

**Step 2: Calculating the Number of Quarters for $20**
Now, to find out how many quarters make up $20, we take the total amount we want to reach, which is $20, and divide it by the value of one quarter. The formula for this calculation is:

\[ \text{Number of Quarters} = \frac{\text{Total Dollar Amount}}{\text{Value of One Quarter}} \]

Plugging in the values, we get:

\[ \text{Number of Quarters} = \frac{20}{0.25} \]

Step 3: Performing the Calculation
When we perform the division, we find that:

\[ \text{Number of Quarters} = 80 \]

So, it takes 80 quarters to make $20.

**Step 4: Addressing the Reference Information**
The reference information you provided mentions a conversion involving weight, which is not directly relevant to the calculation of the number of quarters needed to make $20. The weight of a coin does not affect its value in dollars and cents. The calculation we performed is the standard method for determining the number of quarters required to reach a specific dollar amount.

Step 5: Conclusion
In conclusion, to make $20 using quarters, you would need 80 of them. This is a straightforward calculation based on the value of a quarter and the total amount desired. It's always good to understand the basics of currency and its conversion to ensure accuracy in financial transactions.

Now, let's move on to the translation of the answer into Chinese.
