About these units
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.
Quart (US) (qt (US))
A US quart equals 32 US fluid ounces or 946 milliliters, exactly 1/4 of a US gallon. It is commonly used for milk, juice, motor oil, and household chemicals. The quart's convenient scale makes it ideal for medium-sized liquid quantities—larger than a pint but smaller than a gallon. It remains widely used in American kitchens, automotive maintenance, and everyday shopping. Like other US customary units, the quart persists because consumers and industries have longstanding infrastructures built around it.
