Gallon Per Square Foot Formula:
| From: | To: |
The Gallon Per Square Foot calculation determines the volume of liquid needed to cover a specific area to a certain depth. It's commonly used in irrigation, painting, and construction projects to estimate material requirements.
The calculator uses the formula:
Where:
Explanation: The formula calculates the cubic volume (area × depth) and converts it from cubic feet to gallons using the standard conversion factor of 7.48 gallons per cubic foot.
Details: Accurate volume calculation is essential for proper project planning, material estimation, cost calculation, and avoiding waste in various applications including landscaping, painting, and liquid storage.
Tips: Enter the area in square feet and depth in feet. All values must be valid positive numbers. The calculator will provide the result in gallons.
Q1: Why is 7.48 used in the formula?
A: 7.48 is the conversion factor from cubic feet to gallons, as one cubic foot equals approximately 7.48 US gallons.
Q2: Can this calculator be used for metric units?
A: This specific calculator uses imperial units. For metric calculations, you would need to convert to liters using different conversion factors.
Q3: What applications use this calculation?
A: This calculation is commonly used in irrigation planning, painting projects, concrete pouring, pool filling, and any application where liquid volume needs to cover a specific area.
Q4: How accurate is this calculation?
A: The calculation is mathematically precise based on the inputs provided. Accuracy depends on the precision of your area and depth measurements.
Q5: Does this account for material absorption or evaporation?
A: No, this calculation provides the theoretical volume. In practice, you may need to account for absorption, evaporation, or application efficiency depending on your specific use case.
