Find gallons, liters, weight and fill time for a tub, trough, aquarium or round container measured in inches.
How it works
Cubic inches divided by 231 gives gallons. Weight uses 8.34 lb per gallon.
Before you order
- Measure the water level, not the rim.
- Check floor and stand ratings for big containers, since water gets heavy quickly.
- Time a bucket to find your real hose flow.
Common questions
How is this different from pool volume?
This handles small containers measured in inches and adds weight and fill time. Use the pool calculator for gallons in a sloped pool.
What about non-rectangular shapes?
Split into boxes and cylinders and add them together.
