A gigaliter (GL) is a unit of volume in the metric system equal to one billion liters (109 L).
It can be challenging to visualize just how large a single gigaliter (GL) really is.
To put its immense scale into perspective, one gigaliter is the same as:
This massive scale is why the gigaliter is used for measuring things like a city's water supply or the capacity of a reservoir.
The gigaliter is a standard unit for measuring large-scale water resources and consumption.
You'll often see it used when discussing:
For example, Sydney Harbour contains roughly 500 gigaliters of water.
Measuring volumes in gigaliters is vital for professionals in:
The gigaliter fits neatly within the International System of Units (SI). The prefix "giga" means a factor of one billion.
This makes the conversions straightforward:
It is also equivalent to one million cubic meters (1,000,000 m3) and one-thousandth of a cubic kilometer (0.001 km3).
This makes it a perfect unit for measuring volumes that are too large for liters but smaller than a whole cubic kilometer.
