Frequently Asked Questions

How many gallons are in a cubic meter?

One cubic meter equals 264.17 US gallons. This is also exactly 1000 liters.

How do I calculate my pool volume in gallons?

First calculate the volume in cubic meters: length × width × average depth (all in meters). Then multiply by 264 to get gallons. A 10m × 5m × 1.5m pool = 75 m³ = 19,813 gallons.

How many cubic meters is a 10,000 gallon pool?

A 10,000 gallon pool equals 37.85 cubic meters. This is a typical small to medium residential pool.

How much water does my water meter measure?

Water meters typically measure in cubic meters (m³). Multiply the reading by 264 to get gallons. A reading of 5 m³ means you used 1,321 gallons.

How much does a cubic meter of water weigh?

One cubic meter of water weighs exactly 1000 kg (1 metric ton or about 2,205 pounds). This is useful for calculating tank loads and structural requirements.

What's the difference between cubic meters and liters for pools?

They measure the same thing at different scales. 1 m³ = 1000 liters. Pools are usually expressed in m³ for simplicity; a "50,000 liter pool" is easier to say as "50 m³ pool."
