About these units
Fluid Ounce (US) (fl oz (US))
A US fluid ounce is approximately 29.5735 milliliters. It is not a unit of weight, despite sometimes being confused with the avoirdupois ounce. In beverage serving sizes, cooking, and pharmaceuticals, the fluid ounce provides a flexible unit for small to medium volumes. It serves as the basis for bartending measurements, packaging labels, and nutritional information. Its precise value derives from the US gallon, making the fluid ounce a key link in the US customary volume system.
Cubic Kilometer (km³)
A cubic kilometer represents one billion cubic meters, making it a colossal volume unit used in geology, hydrology, glaciology, and planetary science. Large lakes, ice sheets, magma chambers, and atmospheric water content are often measured in km³. Earth's total ocean volume—about 1.335 billion km³—illustrates the unit's utility in describing planetary-scale systems. The km³ gives scientists a manageable number when dealing with natural features too massive for cubic meters or liters to express conveniently.
