1. What is a Pizza Size Price Calculator?

Definition: This calculator determines the price per square inch of pizza based on its total cost and diameter.

Purpose: It helps consumers compare pizza value between different sizes and prices to make informed purchasing decisions.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( P \) — Price per square inch (USD/in²)
• \( C \) — Total pizza cost (USD)
• \( A \) — Pizza area (in²), calculated as \( π × r² \) where \( r \) is radius (diameter/2)

Explanation: The total cost is divided by the pizza's area to determine how much you're paying per square inch of pizza.

3. Importance of Price per Square Inch

Details: Larger pizzas often provide better value as the area increases with the square of the radius while cost typically increases linearly.

4. Using the Calculator

Tips: Enter the total pizza cost in USD and the diameter in inches. All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Why calculate price per square inch?
A: It standardizes comparison between different pizza sizes and prices to determine the best value.

Q2: Does this account for crust differences?
A: No, this is a basic calculation assuming uniform thickness. Thicker crusts may affect actual value.

Q3: Should I always choose the lowest price per square inch?
A: Not necessarily - consider your appetite, toppings quality, and personal preferences too.

Q4: How accurate is this for non-circular pizzas?
A: For square/rectangular pizzas, calculate area as length × width instead.

Q5: Does this include toppings or just base price?
A: Use the total price you pay, including all toppings and fees, for accurate comparison.
