Quick formulas
- US gallons → litres: × 3.785
- Imperial gallons → litres: × 4.546
- Litres → m³: ÷ 1,000
- Pool volume (m³) = length × width × average depth (all in metres)
How many loads for my tank or pool?
Divide your tank or pool volume by the load size and round up. Example: a 50 m³ pool ÷ 9.46 m³ (a 2,500 US-gallon load) = 5.3 → 6 loads. Or use the pool and tank calculators.
