Important Considerations for Potato Yield:
These are general estimates. The actual yield can vary significantly based on:
**Potato Variety:** Starchy (e.g., Russet), waxy (e.g., Red Bliss), or all-purpose (e.g., Yukon Gold) potatoes can have different densities and water content.
**Size of Dice/Slice:** Smaller pieces will pack more densely into a cup, yielding a slightly higher cup measurement for the same weight compared to larger chunks.
**Amount of Peeling:** The thickness of the peel removed will affect the final yield.
As a rough guideline, 1 pound of potatoes typically yields about 3 to 3.5 cups when peeled and diced into 1/2-inch pieces.
"1 medium potato" is subjective but is often considered to be around 5-6 ounces (140-170 grams).
For recipes where potato quantity is critical, it's best to measure by weight if specified, or prepare a little extra if measuring by volume.
