About gallons
The gallon is a unit with a split personality. The US Gallon (approx. 3.785 L) is based on the pre-1824 English wine gallon. The Imperial Gallon (approx. 4.546 L) used in the UK is about 20% larger. This divergence happened when Britain updated its standards in 1824, but the newly independent US stuck with the old wine gallon. Today, the US gallon is the standard for fuel and milk in the United States. gallons are commonly used in Gasoline sales (US), Milk jugs (US), Paint buckets, and Water consumption tracking, Aquarium sizes.
A large milk jug in the US is 1 gallon.
About cubic meters
The cubic meter (m³) is the SI derived unit of volume. It represents the space occupied by a cube with edges of one meter. It is a massive unit compared to liters, equal to 1,000 liters. It is primarily used in industry, utility billing (water and gas), and shipping (freight volume). One cubic meter of water weighs exactly one metric ton. cubic meters are commonly used in Water bills, Natural gas meters, Concrete and soil delivery, and Shipping containers, Swimming pool volume.
A standard hot tub holds about 1.5 cubic meters of water.
