* Weight vs. Value: Quarters are measured by their weight (grams) and their monetary value (dollars).
* Fluctuations: The weight of a quarter can slightly vary due to wear and tear.
Instead of asking how many quarters equal 200 grams, you could ask:
* How many grams does a quarter weigh? A standard US quarter weighs about 5.67 grams.
* How many quarters are needed to make $20? Since a quarter is worth $0.25, you'd need 80 quarters to make $20.
