What This Pool Gallons Calculator Helps You Do
Use this gallons per square foot calculator to convert between area, depth, and water volume. It is a practical way to estimate how much water a pool, tank, basin, or coated surface will hold when you know the footprint and fill depth.
How to Pool Gallons Calculator
- Choose the value you know - Start with the area, the depth, or the total gallons depending on the situation.
- Keep the units consistent - Use feet for depth and square feet for area so the conversion stays simple.
- Let the calculator convert - The calculator applies the gallon-per-cubic-foot conversion automatically.
- Use the result for planning - Read the gallons per square foot, total gallons, or required area depending on the mode.
Pool Gallons Calculator Formula
| Symbol | Definition | Unit |
|---|---|---|
| Area | Surface area | ft2 |
| Depth | Water depth | ft |
| 7.48052 | Gallons in one cubic foot of water | gal/ft3 |
Working Examples for Pool Gallons Calculator
- area: 240
- depth: 0.333
- gallons: 0
- gpsf: 0
Result: Gallons = 597.84 gal
Each square foot holds a measurable amount of water at this depth. The estimate is 597.84 gal.
- area: 0
- depth: 1
- gallons: 80
- gpsf: 0
Result: Area = 10.69 ft2
A one-foot depth lets you back into the required footprint from the gallons figure. The estimate is 10.69 ft2.
- area: 150
- depth: 0.5
- gallons: 0
- gpsf: 0
Result: Gallons = 561.04 gal
The pond volume is simply area multiplied by depth and then converted to gallons. The estimate is 561.04 gal.
- area: 100
- depth: 0
- gallons: 20
- gpsf: 0
Result: Depth = 0.03 ft
Spreading a small gallon count over a known area produces a shallow coating depth. The estimate is 0.03 ft.
How to Interpret Your Results
| Range | Meaning | Action |
|---|---|---|
| Shallow depth | Low gallons per square foot | Good for thin coatings, small pond depths, or shallow holding basins. |
| Moderate depth | Typical water coverage | Useful for pool fills, tanks, and general volume estimates. |
| Greater depth | Higher gallons per square foot | Check containment, weight loading, and fill capacity before proceeding. |
