A gallon (gal) is a unit of volume, most commonly associated with the imperial and US customary systems of measurement.
It is equal to 128 Fluid Ounces (fl-oz).
A common point of confusion is the difference between the US gallon and the imperial gallon (used in the UK and other Commonwealth nations).
They are not the same size!
This difference stems from historical definitions that were standardized differently in the US and Britain during the 18th and 19th centuries.
So, if you're comparing fuel efficiency, remember that "miles per gallon" ratings are based on different-sized gallons!
The word "gallon" has a rich history, tracing its roots back through several languages.
It originates from the Old Northern French word galon, which referred to a liquid measure.
This term is believed to have originated from the Gallo-Roman word gallēta, meaning a "pail" or "bucket." The ultimate origin likely goes back to a Celtic word, highlighting the unit's long-standing use in European trade and daily life for centuries.
While we typically associate the gallon with liquids, there is also a US dry gallon.
This unit, not commonly used today, is equivalent to one-eighth of a bushel, or about 4.405 liters. It was historically used to measure dry goods such as grain or fruit.
This is also why the famous "10-gallon hat" is a misnomer; its name doesn't refer to its volume.
Instead, it is thought to originate from the Spanish word galón, meaning "braid," which refers to the braided band on the hat.
A cubic meter (m3) is a unit of volume in the metric system, equal to one thousand liters (1000 L).
It is the volume of a perfect cube with sides that are exactly one meter long. The plural form is cubic meters.
It can be challenging to visualize a cubic meter in your mind. Still, a few everyday examples help clarify the concept. One cubic meter is roughly the size of:
The cubic meter (m3) is the SI unit for volume — the global standard used in science, engineering, and international trade.
Because it's based on the meter (the SI unit of length), it fits neatly into a consistent measurement system.
This makes it practical for measuring large amounts — from the concrete for a building to the capacity of a shipping container.
The cubic meter has a direct and valuable relationship with mass.
For example, one cubic meter of pure water at its maximum density has a mass of almost exactly 1,000 kilograms (or one metric ton).
The unit is also used in specialized fields. When measuring stacked firewood, a cubic meter is often called a "stere."
While it's not an official SI unit, the stere is still commonly used in the forestry and timber industries.
