1. What is the Soil Volume Formula?

The soil volume formula calculates the capacity of cylindrical pots using the standard cylinder volume equation. This helps gardeners determine how much soil they need to fill their pots.

2. How Does the Calculator Work?

The calculator uses the cylinder volume equation:

Where:

• \( \pi \) — Mathematical constant (approximately 3.1416)
• \( Radius \) — Radius of the pot (in feet)
• \( Height \) — Height of the pot (in feet)

Explanation: The equation calculates the volume by multiplying the area of the circular base (πr²) by the height of the cylinder.

3. Importance of Soil Volume Calculation

Details: Knowing the soil volume helps in proper plant selection, determining water requirements, and calculating fertilizer needs for container gardening.

4. Using the Calculator

Tips: Measure the radius (half of diameter) and height of your pot in feet. Enter these values to get the soil volume in cubic feet.

5. Frequently Asked Questions (FAQ)

Q1: How do I measure my pot's dimensions?
A: Measure the diameter across the top, divide by 2 for radius. Measure from base to rim for height.

Q2: What if my pot isn't perfectly cylindrical?
A: This calculation works best for true cylinders. For tapered pots, use average dimensions.

Q3: How do I convert cubic feet to gallons?
A: Multiply cubic feet by 7.48 to get US gallons.

Q4: How much soil should I buy?
A: Purchase slightly more than the calculated volume to account for settling.

Q5: Does this work for rectangular planters?
A: No, for rectangular containers use Length × Width × Height.
