First, measure inside tank dimensions. Use a tape measure for accuracy. Record length, width, and height. Then select your measurement unit. Choose output unit preference. Click calculate for instant results.
Remember decorations displace water. Subtract about 10-15% for substrate. Adjust for internal equipment too. Actual water volume is typically less. This affects treatment dosing significantly.
The fundamental formula for calculating aquarium volume is:
This basic formula requires unit conversion:
Our calculator handles all conversions automatically. Simply enter your dimensions and get results.
The aquarium volume calculator processes your inputs mathematically. First, it collects three dimensions. Then it checks selected units. Next, it applies appropriate conversion factors. For centimeters, it divides by 1000. Alternatively, for inches it uses 231 divisor.
Finally, it converts to required output. The system handles liters to gallons. Results display instantly. This automation prevents calculation errors. Moreover, it saves significant time.
| Tank Name | Dimensions (L×W×H) | Volume (Liters) | Volume (Gallons) |
|---|---|---|---|
| Nano Tank | 30×20×20 cm | 12 L | 3.2 gal |
| Small Aquarium | 45×30×30 cm | 40.5 L | 10.7 gal |
| Medium Aquarium | 60×30×35 cm | 63 L | 16.6 gal |
| Standard 20 Gallon | 76×30×30 cm | 68.4 L | 18 gal |
| Large Aquarium | 120×45×45 cm | 243 L | 64.2 gal |
| Extra Large Tank | 180×60×60 cm | 648 L | 171.2 gal |
Accurate volume knowledge is crucial for fish health. It ensures proper medication dosing. Stocking levels depend on tank capacity. Filter and heater selection requires volume. Water change quantities need this information. Overall, it maintains ecosystem balance.
Divide complex shapes into sections. Calculate each part separately. Then sum all volumes together. Bow front tanks need special formulas. Cylinder volumes require different calculations. Our calculator handles standard shapes only.
No, calculated volume is total space. Decorations displace significant water. Rocks and substrate reduce capacity. Always subtract 10-20% for decorations. This gives actual water volume. Adjust treatments accordingly.
Absolutely. Volume calculation remains identical. Saltwater doesn't change mathematics. However, salinity affects weight measurements. Our calculator works for all aquarium types. Including freshwater and marine setups.
Recalculate after major changes only. When adding substantial decorations. After tank upgrades or modifications. Otherwise, volume remains constant. Bookmark your result for reference. Regular recalculations aren't necessary.
