Sizing a 10-gallon tank in liters
10 US gallons is 37.85 liters. US aquarium and storage-tank sizes use this gallon; in imperial gallons the same number would be 45.46 liters, a difference of 7.61 liters.
| What you are filling | Volume | Weight of the water |
|---|---|---|
| 10 US gallons | 37.85 L | about 37.8 kg (83.5 lb) |
| 10 imperial gallons | 45.46 L | about 45.4 kg (100.2 lb) |
| 10 US gallons filled to 90% | 34.07 L | about 34.1 kg |
- A "10-gallon" aquarium is a nominal size: the glass box holds about 37.9 liters, and gravel, rocks and the gap below the rim leave less water than that.
- Water weighs close to 1 kg per liter, so a full 10-gallon tank puts about 38 kg on its stand before the glass and substrate are counted.
- When a water-conditioner or fertiliser label doses "per 10 gallons", check whether it means US or imperial gallons before you scale it to liters.
Four 10-liter buckets (40 L) overshoot 10 US gallons by about 2 liters, so 10 gallons is a little under four buckets.

Volume uses US liquid gallons for “gal”. Imperial gallons use a different factor.
A quick note before you use the number
“gal” in this calculator means US liquid gallon. An imperial gallon is a different size, so do not substitute one standard for the other.
